'make test' errors on tests not included in release tarball

[hlein]

Bug and expected behavior

• make test produces some errors because Makefile.in's default test target includes test-private-lib and test-fnetfilter; the release tarball has no such subdirectories under test/.
• Those are present in the git repo, but not in the release tarballs; Makefile.in's DISTFILES_TEST= enumerates test/ dirs to package, excluding those two.
• The right/expected behavior would be some combination of 1) including more test/ subdirs in release tarballs, 2) pruning the list of test-* targets included in the default test: target in Makefile.in, 3) checking for the presence of, and gracefully handling the lack of, individual test/ subdirs.

Reproduce
Steps to reproduce the behavior:

1. unpack tarball such as firejail-0.9.64.tar.xz
2. configure and compile
3. run make test
4. Errors such as:

cd test/private-lib; ./private-lib.sh | grep TESTING
...
/bin/sh: line 0: cd: test/private-lib: No such file or directory
/bin/sh: ./private-lib.sh: No such file or directory
...
cd test/fnetfilter; ./fnetfilter.sh | grep TESTING
...
/bin/sh: line 0: cd: test/fnetfilter: No such file or directory
/bin/sh: ./fnetfilter.sh: No such file or directory
...
make: *** [Makefile:232: test-private-lib] Error 1
make: *** Waiting for unfinished jobs....
make: *** [Makefile:265: test-fnetfilter] Error 1

Environment

• Gentoo Linux
• firejail-0.9.64
