Subject: [PATCH] selinux_bprm_committed_creds: use __wake_up_parent()

(depends on ptrace-__ptrace_detach-do-__wake_up_parent-if-we-reap-the-tracee.patch
 which exports __wake_up_parent)

Spotted by Valdis.Kletnieks@xxxxxxx

selinux_bprm_committed_creds() should not play with ->wait_chldexit, now
that __wake_up_parent() is exported change the code to use this helper.
