qmake: Centralize TARGET sanitization in default_post.prf

Shared between UNIX and Win generators, and allows prfs after
default_post to rely on sane TARGET and DESTDIR values.

This allows us to clean up the DESTDIR logic in testcase.prf,
which was completely busted. Doing the two in separate commits
is unfortunately not possible as the old testcase.prf logic
was so broken it would barf if only looked at.
