tests fail on FreeBSD

[joshrabinowitz]

We should have some tests of git-secret on some flavor(s) of *BSD.

Can we do this with travis-ci?

Steps to reproduce:

• Install FreeBSD (I used 11.2 RELEASE on VirtualBox)
• install gpg, gawk, bash, gmake from pkg repos ('make' doesn't work at all)
• fetch git-secret source from github
• cd git-secret
• gmake clean build test

What happens?

• all tests fail

What were you expecting to happen?

• tests pass

Any logs, error output, etc?

not ok 1 run 'add' normally
...
#  `install_fixture_key "$TEST_DEFAULT_USER"' failed
...
and so on. All tests fail.

What versions of software are you using?
