t0003: do not chdir the whole test process

Moving to some other directory and letting the remainder of the test
pieces to expect that they start there is a bad practice.  The test
that contains chdir itself may fail (or by mistake skipped via the
GIT_SKIP_TESTS mechanism) in which case the remainder may operate on
files in unexpected places.
