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.
