tools/bpftool: use version from the kernel source tree Bpftool determines it's own version based on the kernel version, which is picked from the linux/version.h header. It's strange to use the version of the installed kernel headers, and makes much more sense to use the version of the actual source tree, where bpftool sources are. Fix this by building kernelversion target and use the resulting string as bpftool version.

prefix ?= /usr/local
tools: bpftool: unify installation directories Programs and documentation not managed by package manager are generally installed under /usr/local/, instead of the user's home directory. In particular, `man` is generally able to find manual pages under `/usr/local/share/man`. bpftool generally follows perf's example, and perf installs to home directory. However bpftool requires root credentials, so it seems sensible to follow the more common convention of installing files under /usr/local instead. So, make /usr/local the default prefix for installing the binary with `make install`, and the documentation with `make doc-install`. Also, create /usr/local/sbin if it does not exist. Note that the bash-completion file, however, is still installed under /usr/share/bash-completion/completions, as the default setup for bash does not attempt to load completion files under /usr/local/.

tools/bpftool: fix bpftool build with bintutils >= 2.9 Bpftool build is broken with binutils version 2.29 and later. The cause is commit 003ca0fd2286 ("Refactor disassembler selection") in the binutils repo, which changed the disassembler() function signature. Fix this by adding a new "feature" to the tools/build/features infrastructure and make it responsible for decision which disassembler() function signature to use.

tools: bpftool: create "uninstall", "doc-uninstall" make targets Create two targets to remove executable and documentation that would have been previously installed with `make install` and `make doc-install`. Also create a "QUIET_UNINST" helper in tools/scripts/Makefile.include. Do not attempt to remove directories /usr/local/sbin and /usr/share/bash-completions/completions, even if they are empty, as those specific directories probably already existed on the system before we installed the program, and we do not wish to break other makefiles that might assume their existence. Do remvoe /usr/local/share/man/man8 if empty however, as this directory does not seem to exist by default.
