[PATCH] test: create dtach's session socket in $TEST_TMPDIR

[Tomi Ollila]

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.
---
Gymnastics required in ${TMPDIR:-/tmp} as mktemp --tmpdir is not portable ;/.
