[PATCH] Fix a bug of parsing "exe=" in function parse_user()

[Peng Haitao]

Hello steve,

The value of "exe=" which is not in double quotation, cannot be right gotten.

For example:
# echo "type=USER_ROLE_CHANGE msg=audit(1219940034.985:363068): user pid=24741 uid=0 auid=0 subj=root:system_r:semanage_t:s0-s0:c0.c1023 msg='op=delete SELinux user mapping acct="sltester" old-seuser=? old-role=? old-range=? new-seuser=? new-role=? new-range=? exe=/usr/sbin/semanage (hostname=?, addr=?, terminal=? res=failed)'" | ausearch -x "/usr/sbin/semanage"
<no matches>
