valgrind: skip 14 ptests in 3.22

valgrind: skip 14 ptests in 3.22

Sort the ptest depenencies into a somewhat alpahbetical order.
Add python3-compile for ptests.

Add softlinks for cachegrind to eliminate a warning seen in those tests.

The folowing tests fail after the 3.22 update:
   memcheck/tests/linux/dlclose_leak-no-keep
   memcheck/tests/linux/dlclose_leak
   memcheck/tests/wrap1
   memcheck/tests/wrap2
   ...
   memcheck/tests/wrap8
   cachegrind/tests/wrap5
   massif/tests/bug469146
   massif/tests/new-cpp
   massif/tests/overloaded-new

Omit these tests until they are fixed.
