Regression tests skipped when running on Ubuntu in Cirrus CI. JUnit report contains a reason of skip - Seem a problem exist because FUSE kernel module is not loaded before a testing. https://cirrus-ci.org/guide/linux/

Commit "Use generic os name in tests" (1f70f876d670704bd0422fe1e27d12177b189527) accidentally disabled testing on FreeBSD by adding double negation to condition that enables code for operating systems with fusermount(1). However fusermount(1) is not available on FreeBSD and therefore all regression tests were skipped. Fixes #93
