[PATCH v2 4/7] test-lib: set $TRASH_DIRECTORY earlier

[SZEDER Gábor]

A later patch in this series will need to know the path to the trash
directory early in 'test-lib.sh', but $TRASH_DIRECTORY is set much
later.  Furthermore, the path to the trash directory depends on the
'--root=<path>' option, which, too, is parsed too late.

Move parsing '--root=...' to the early option parsing loop, and set
$TRASH_DIRECTORY where the other test-specific path variables are set.
