test: create dtach's session socket in $TEST_TMPDIR

Due to 108-character limit in unix domain socket path this change
is required; it is more probable that length of ${TMPDIR:-/tmp} is
shorter than length of path to the current directory of notmuch test
source directory. One can expect to create reasonable-length unix
domain sockets wherever $TMPDIR points to.
