libc: Default LIBC_INSTALL_PREFIX to ${CMAKE_INSTALL_PREFIX} 
b22f448c21 added a rule to install libllvmlibc.a to
${LIBC_INSTALL_PREFIX}/${LIBC_INSTALL_LIBRARY_DIR}, which will be /lib
by default, which is disruptive to builds that stay within a user's
/home holder:

  $ ninja install
  ...
  -- Installing: /lib/libllvmlibc.a
  CMake Error at projects/libc/lib/cmake_install.cmake:54 (file):
    file INSTALL cannot copy file
   "/home/nathan/cbl/github/tc-build/build/llvm/stage1/projects/libc/lib/libllvmlibc.a"
    to "/lib/libllvmlibc.a": Permission denied.
  Call Stack (most recent call first):
    projects/libc/cmake_install.cmake:51 (include)
    projects/cmake_install.cmake:47 (include)
    cmake_install.cmake:76 (include)
  ...

Change LIBC_INSTALL_PREFIX's default value to ${CMAKE_INSTALL_PREFIX} so
that 'ninja install' does not attempt to install anything outside of the
user's requested installation location.
