Remove bad_acq_stars regress diff hack

The regress script was set to rewrite the starcheck output to make the
bad_acq_stars.rdb path look like the previous value to ignore the
diff.  This is moot now.
Update Makefile SRC path

This reduces the SHA1SUM diffs as the full path for the starcheck src
files will not be used to calculate the sum.
Add HOSTNAME to regression info and use ska_version in sha1sum
Add ska_version and SKA location to regress notes
Merge pull request #41 from sot/regress_tweaks

remove full path when calculating regression output sha1sums
