valgrind: do not strip internal preload libraries and executables

Implement the suggestions laid out in README_PACKAGERS, mainly by preventing
the stripping of the internal vgpreload*.so libraries.

Also retain the symbol information of valgrind's private helper executables
and enable LTO as suggested in the packagers readme.
