Simplify and add to the QA valgrind suppressions file
Simplify and add to the QA valgrind suppressions file

Discovered the "..." magic incantation which makes several
things easier in the valgrind suppressions file - able to
collapse several dlopen cases into one as a result.  Also,
the pmConfig case becomes easier now (and not hard-coding
a 32-bit-libraries-only path for some platforms too).

Add in some initial suppressions for readline and NSS from
testing pmdarpm with dbpmda a bit.
