pgsql: Exclude Threadsanitizer instrumentation in exit check

Exclude Threadsanitizer instrumentation in exit check

When building libpq there is a check to ensure that we're not
linking against code that calls exit(). This check is using a
heuristic grep with exclusions for known false positives. The
Threadsanitizer library instrumentation for function exits is
named such that it triggers the check, so add an exclusion.

This fix is only applied to the Makefile since the meson build
files don't yet have this check. Adding the check to meson is
outside the scope of this patch though.
