tests/test-rebase-collapse

Fixed a bashism with the use of $RANDOM in hgeditor.

The variable $RANDOM is not POSIX so a portable /bin/sh may not define
it.  When creating a directory with a random name it's better to use
mktemp, which, even though is not POSIX, exists in common Unixes
including Linux, OpenBSD, FreeBSD and MacOS X.
