selftests/memfd: delete unused declarations

Browse source 
Commit 32d118ad50 ("selftests/memfd: add tests for F_SEAL_EXEC"):
- added several unused 'nbytes' local variables

Commit 6469b66e3f ("selftests: improve vm.memfd_noexec sysctl tests"):
- orphaned 'newpid_thread_fn2()' forward declaration
- orphaned 'join_newpid_thread()' forward declaration
- added unused 'pid' local in sysctl_simple_child()
- orphaned 'fd' local in sysctl_simple_child()
- added unused 'fd' in sysctl_nested_child()

Delete the unused locals and forward declarations.
