The current FOUND_VAR for FindLibEdit is libedit_FOUND but wasn't set by
find_package_handle_standard_args. However this isn't valid for the
package name.
The argument for FOUND_VAR is "libedit_FOUND", but only "LibEdit_FOUND" and
"LIBEDIT_FOUND" are valid names.
This fixes all the variables set by FindLibEdit to match the desired
naming scheme.
The package name is LibEdit, so we should use that name in the call to
find_package_handle_standard_args. Failing to do so results in the
standard_args (such as the one telling us whether REQUIRED was used in
the find_package invocation) not being handled.

Use proper cmake techniques to detect where the libedit package resides.
This allows for the use of libedit from an alternative location which is
needed for supporting cross-compilation.
