[PATCH 1/2] test-lib: group system specific FIFO tests by system

[Michael J Gruber <git@grubix.eu>]

test-lib determines whether a file-system supports FIFOs and needs to do
special casing for CYGWIN and MINGW. This separates those system
specific settings from those at more central place.

Set mkfifo()  to false in the central system specific place so that the
same test works everywhere.
