Regression swap test: skip with failure if on tmpfs

Browse source 
The regression swap test attempts to activate a swap file in a
directory under where tmpdir is set in uservars.inc; if this is a
tmpfs filesystem, this will fail (it's kind of silly to create a
swap file on a tmpfs, a memory-backed filesystem). This patch adds a
check to the swap test script and skips the tests if it detects it's
on tmpfs and marks the test as a failure if the check fails.
