test: Use fork() on MacOS X

Browse source 
MacOS X 10.7 (and maybe some previous versions, too) can fork()
processes which use CoreGraphics. This makes it possible for
cairo-test-suite to withstand a test crash without killing the whole
suite.

The old behavior is still available using the '-f' (foreground)
option.
