Subject: [PATCH 2/4] bpftool: Complete libbfd feature detection

Commit 6e8ccb4f624a7 ("tools/bpf: properly account for libbfd variations")
sets the linking flags depending on which flavor of the libbfd feature was
detected.

However, the flavors except libbfd cannot be detected, as they are not in
the feature list.

Complete the list of features to detect by adding libbfd-liberty and
libbfd-liberty-z.

Fixes: 6e8ccb4f624a7 ("tools/bpf: properly account for libbfd variations")
