Amin Vakil 879b3353d0 selftests: proc: include fcntl.h in proc-pidns ...

proc-pidns.c uses open() and O_* flags, but does not include
<fcntl.h>. This breaks the proc selftests build with errors such as:

  error: implicit declaration of function 'open'
  error: 'O_WRONLY' undeclared
  error: 'O_CREAT' undeclared
  error: 'O_RDONLY' undeclared

Include <fcntl.h> to provide the declaration and flag definitions.

Fixes: 5554d820f7 ("selftests/proc: add tests for new pidns APIs")
Tested with:
  make -C tools/testing/selftests TARGETS=proc
