[Buildroot] Makefile: follow symlinks when excluding files from being stripped.

[Umesh Nerlige Ramappa]

In BR2_STRIP_EXCLUDE_FILES="libfoo.so" libfoo.so is mostly a symlink
pointing to the actual library file. The actual library file is still
stripped. While specifying the actual library file as libfoo.so.x.x
will work just fine, a user of buildroot need not know what version
of the library is being picked.
