If not TMPDIR is set by the user then the test grub_cmd_cryptomount
creates about 20 directories named *LUKS*_test* in the root directory
and leaves them there when the test ends.
Initialize in the test script the variable TMPDIR to /tmp if it is not
set or if it set to empty text. To be consistent with the usage of
${TMPDIR:-/tmp} in the script, use ${TMPDIR:=/tmp} not ${TMPDIR=/tmp}.
Further delete each created directory as soon as the command of its
test case is finished.
