mtrace: Fix output with PIE and ASLR [BZ #22716]
Record only the relative address of the caller in mtrace file. Use
LD_TRACE_PRELINKING to get the executable as well as binary vs
executable load offsets so that we may compute a base to add to the
relative address in the mtrace file. This allows us to get a valid
address to pass to addr2line in all cases.
Fixes BZ #22716.
