Subject: [PATCH] tests: include fcntl.h for open(), O_RDWR, O_CLOEXEC and
 O_CREAT

musl libc (unlike glibc) requires explicitly incuding fcntl.h to define open(),
O_RDWR, O_CLOEXEC and O_CREAT. Otherwise the build fails with the errors:

| ../weston-9.0.0/tests/weston-test-fixture-compositor.c: In function 'wait_for_lock':
| ../weston-9.0.0/tests/weston-test-fixture-compositor.c:135:7: warning: implicit declaration of function 'open'; did you mean 'popen'? [-Wimplicit-function-declaration]
