Log Message:
Fix anonymous memory object leak for sigcode.
- Repeating "modload compat_linux && /emul/linux/bin/ls && modunload
compat_linux"
will reproduce this problem.
- It cause in exec_sigcode_map(), anon-object for sigcode was created at
first exec, but it remained even after exec_remove.
- Fixed that the anon-object for sigcode is created at exec_add(), and the
anon-object reference is removed at exec_remove().
- sigobject_lock is no longer needed since it is locked by exec_lock.
