Add a few more status tests

Here are a few more tests for git status. The first one makes sure that --porcelain uses paths based on the root, it makes sense on top of 14ed05d (t7508-status.sh: Add tests for status -s, 2009-11-27) or later.

The second one checks long, short and porcelain with color. It makes sense on top of 3fe2a89 (status -s: obey color.status, 2009-12-05), although one test will fail without the later 8661768 (status: reduce duplicated setup code, 2009-12-07) and predecessor.

Remarks:
- There's not a single merge related status test so far.
- There's no test with -z because I don't know what it's suppoded to (besides the obvious thing): should it turn off color automatically but not relativePaths? Or should it switch to --porcelain -z?

Depending on the answer to the latter I have to do one more fixup to wt-status.c (and write another test).

Thanks:
to J6t for pointing me to decrypt_color()

t7508-status: status --porcelain ignores relative paths setting
t7508-status: test all modes with color
