Zdenek Kabelac 76cc477fba tests: no warn if test does not need thin_repair
Set LVM_TEST_THIN_REPAIR_CMD to /bin/false for test which
doesn't need it.

This way - even if on the system there is no such tool present,
test will not result with warning about missing tool.

Also remove from Makefile settings of TEST vars which are set in
through /lib/paths  - this also allows to override them in test.
