[patch] Modify flag's value in tapset's probe delete_module

["Zhaolei" <zhaolei@cn.fujitsu.com>]

Hi, everyone

In the probe delete_module(syscalls.stp), function _module_flags_str
 (aux_syscalls.stp) is used for converting the flags to string. But the
 returned string is different from the man page of delete_module:

delete_module's flag values in "man delete_module"(RHEL5,IA64) is O_TRUNC
 and O_NONBLOCK, but in probe delete_module, flag's value is WAIT and FORCE
 (From other non-intel-arch?).

Is there anyone knows why tapset uses WAIT/FORCE values for delete_module's
 flag, please tell me(or I will modify it unify with man).

And there may be another problem exists in delete_module's probe:
O_TRUNC and O_NONBLOCK's value is different between architectures, so I
 think it is better using defined value for compare with flag's value.
 (It we use static value as 2048/512, it will get different result across
 architectures):

I write a patch for this problem:
and if no objection, I will commit it.
