perf symbols: Kill dso__build_id_is_kmod()
The commit e7ee40475760 ("perf symbols: Fix symbols searching for module
in buildid-cache") added the function to check kernel modules reside in
the build-id cache. This was because there's no way to identify a DSO
which is actually a kernel module. So it searched linkname of the file
and find ".ko" suffix.
But this does not work for compressed kernel modules and now such DSOs
have correct symtab_type now. So no need to check it anymore. This
patch essentially reverts the commit.
