Remove parser of query_module syscall

Since query_module syscall is present only in kernels before Linux 2.6
and strace does not support those kernels, there is no use to keep this
parser any longer.

* bjm.c: Do not include <sys/*>, "xlat/qm_which.h",
and "xlat/modflags.h".
(MOD_*, QM_*, module_symbol, module_info, SYS_FUNC(query_module)):
Remove.
* linux/dummy.h (sys_query_module): Add stub alias.
* xlat/modflags.in: Remove.
* xlat/qm_which.in: Remove.
