test.sh asserts vtysh, libfrr.so and the per-subpackage daemon binary,
and cross-checks the release in "vtysh --help" against the package
version. test-version.sh overrides the generic scan, which cannot work
for frr-pythontools.
Package/frr-zebra installed libmlag_pb.so* with INSTALL_BIN, which
dereferences symlinks and so tripped the SONAME-symlink check; use
$(CP) instead.
