asterisk.py:  Use env var AST_WORK_DIR for temp directory if avail

It's possible that on some systems, the /tmp directory is not
mounted on a tmpfs.  In a docker container for instance, it may
be part of the container's write-only layer.  This can make things
slow enough that the already-time-sensitive testsuite can report
false failures.  This patch allows the user to specify a directory
in which the testsuite will create it's temp files.  The user
could then create a directory and mount a tmpfs on it for the
testsuite to use.

Example:
$ mkdir /tmp/testsuite
$ mount -t tmpfs -o size=4g,noatime tmpfs /tmp/testsuite
$ export AST_WORK_DIR=/tmp/testsuite
$ ./runtests.py <yada, yada>
$ umount /tmp/testsuite
