Commit 5330966 replaced local static buffer with malloc allocated
lib_get_pathbuffer. This however prevents the usage of sizeof(buffer)
in the follow up read function, therefore the read size has to be
specified as PATH_MAX - 1.
This fixes the functionality of pidof function call (and subsequently
pkill call that uses pidof).
