test: fix build when SHOULD_FORK is false

​

The code in test/cairo-test-runner.c properly takes into account

platforms that do have fork() support, and uses the SHOULD_FORK define

to know whether fork is available or not.

​

However, this SHOULD_FORK macro is used to guard the inclusion of

<unistd.h>, which is needed to get the prototype of other functions

(namely readlink and getppid), that are used in portions of this file

not guarded by SHOULD_FORK.
