[PATCH] do not use SVTYPEMASK to prevent cleaning of PL_fdpid andPL_strtab

The patch disables cleaning of PL_fdpid and PL_strtab by excluding them
from do_clean_all instead of abusing the SvTYPE. Setting the SVTYPEMASK
was giving problems with kurila with some of the recent checks that SVs
passed to av_* function are actually SVt_PVAV (I am not sure why this
only happens in kurila and not in blead). 

Also it uses the return value of sv_clean_all() instead of PL_sv_count.
In some cases (in particular the t/op/threads.t) it appears that
PL_sv_count is incorrect and the previous method would result in an
infinite loop.

Is there a valid reason why PL_sv_count can be different than the number
of SVs as returned by S_visit? If not we could add some asserts that
they are equal and pinpoint the memory leaks of t/op/threads.t
