perf buildid-list: We need to check if a file is ELF first

I.e. before we try to use it as a perf.data file by calling
perf_session__new, otherwise we lose the feature that shows the
build id for the given ELF file, this one:

[root@sandy redhat-perfdata-mtech-15]# perf buildid-list -i /root/.debug/.build-id/97/54896de655b6ac088ec2bf5113b35c06f72709
9754896de655b6ac088ec2bf5113b35c06f72709
[root@sandy redhat-perfdata-mtech-15]# perf buildid-list -i /lib/libc-2.12.so

[root@sandy redhat-perfdata-mtech-15]#
