Implement fcntl F_CREATED_QUERY

Define VKI_F_CREATED_QUERY in vki-linux.h.
Recognize it in PRE(sys_fcntl).
This fixes ltp tests failures. When running:
make ltpchecks TESTS="fcntl40 fcntl40_64
the tests would fail with:
fcntl40: unempty log2.filtered:
==1809471== Warning: unimplemented fcntl command: 1028
