perf trace: Fix the perf trace link location

The install perf_dlfilter.h patch included what seems to be a typo in
the Makefile.perf, which changed the location of the trace link from
'$(DESTDIR_SQ)$(bindir_SQ)/trace' to '$(DESTDIR_SQ)$(dir_SQ)/trace'.

This reverts it back to the correct location.
