Make argv[0] an absolute path so 'wine d:setup' works (2nd try)

[Dan Kegel <dank@kegel.com>]

My last version broke the existing regression tests.
This one doesn't, and I've added a regression test to
make sure argv[0] is an absolute path.

This patch should be reviewed carefully, as I don't really
understand Wine's internals yet.

Changelog:
     * scheduler/process.c: make argv[0] absolute so 'wine d:setup' works
     * dlls/kernel/tests/process.c: verify that argv[0] is absolute and contains drive letter
