tests: Add workaround to allow tests mock fileno on FreeBSD

fileno can be a function and a macro in FreeBSD, depending on whether
the environment in multi-threaded or single-threaded. For single
thread, macro is used. Macro is expanded into a inline code which
accesses private field of file descriptor. This is impossible to
mock in tests.

Pretending that environment is multi-threaded makes fileno function
to be called instead of a macro. Function can be mocked for tests.

BUG=b:237606255
TEST=ninja test
tests pass on two environments:
1) FreeBSD 13.1-RELEASE-p2 GENERIC amd64
2) Debian 5.17.11 x86_64 GNU/Linux
