Revert "Fix incorrect source file name for inlined frames"

Browse Source 
This reverts commit 54d878abcb.

54d878abcb changed the dump_syms format incompatibly. This must be
redone in a multi-step process: the processor must be made to understand
the old and new formats simultaneously and the processor service must be
rebuilt and run with that update before dump_syms output can change to
use the new format.
