Subject: selftests, bpftool: Skip the build test if not in tree
Patch-mainline: v5.5-rc1
Git-commit: 5940c5bf6504f66f57f03f1d0046abfaf2198b3a
References: bsc#1155518

If selftests are copied over to another machine/location
for execution the build test of bpftool will obviously
not work, since the sources are not copied.
Skip it if we can't find bpftool's Makefile.
