tests: A SANITY test prereq for testing if we're root
Some tests depend on not being able to write to files after chmod
-w. This doesn't work when running the tests as root.
Change test-lib.sh to test if this works, and if so it sets a new
SANITY test prerequisite. The tests that use this previously failed
when run under root.
There was already a test for this in t3600-rm.sh, added by Junio C
Hamano in 2283645 in 2006. That check now uses the new SANITY
prerequisite.
Some of this was resurrected from the "Tests in Cygwin" thread in May
2009:

The filesystem we're on supports symbolic links. E.g. a FAT
filesystem doesn't support these. See 704a3143 for details.
