Make prepare_app() safer in non-main threads

Calling prepare_app() from a non-main thread in a multithreaded
process could fail. While labels for other threads were being correctly
set by writing to /proc/<tid>/attr/current, the prepare_app thread used
smack_set_label_for_self() and thus /proc/self/attr/current.

This is easily fixed by reusing label_for_self_internal() so that all
threads are uniformly treated, each using its own tid.
