Junio C Hamano bfdbee9810 tests: use $TEST_DIRECTORY to refer to the t/ directory
Many test scripts assumed that they will start in a 'trash' subdirectory
that is a single level down from the t/ directory, and referred to their
test vector files by asking for files like "../t9999/expect".  This will
break if we move the 'trash' subdirectory elsewhere.

To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can
refer to t/ directory reliably.  This finally makes all the tests use
it to refer to the outside environment.

With this patch, and a one-liner not included here (because it would
contradict with what Dscho really wants to do):

|         echo >&5 "FATAL: Cannot prepare test area"

all the tests still pass, but we would want extra sets of eyeballs on this
type of change to really make sure.

[jc: with help from Stephan Beyer on http-push tests I do not run myself;
 credits for locating silly quoting errors go to Olivier Marin.]
