libshouldbeinlibc: Do not reauthenticate proc port when secure

exec_reauth () is supposed to reauthenticate the given ports and file
descriptors with a new authentication. If the secure flag is set, this
reauthentication is happening for a future exec with the EXEC_SECURE
flag.

Now that the exec server uses proc_reauthenticate_reassign (), the process
reauthentication is done atomically with task reassignment by the exec
server. So stop doing it inside exec_reauth ().

This fixes a vulnerability where a process was able to use its
reauthenticated proc port before it got exec'ed over.
