[PATCH i-g-t] tests/kms_atomic: fix musl compilation

[Kamil Konieczny]

On musl there is already defined PAGE_SIZE and it is casing
compilation error:

../tests/kms_atomic.c: In function 'crtc_invalid_params_fence'
../tests/kms_atomic.c:893:25: error: expected identifier or '(' before numeric constant
  893 |         const ptrdiff_t PAGE_SIZE = sysconf(_SC_PAGE_SIZE);

Change this variable name in order to fix it.
