tests: fill higher bits of integer arguments of fcntl* syscalls

Browse Source 
Check that integer arguments of fcntl and fcntl64 syscalls are decoded
properly by casting them to kernel_ulong_t and filling higher bits.

* tests/struct_flock.c (invoke_test_syscall): Cast "fd" and "cmd"
syscall arguments to kernel_ulong_t, fill their higher 32 bits.
