pm-qa: fix paths for shell scripts

A commit in the repo of pm-qa:

"adf9df9 Fix path to library files and change shebang line"

Changed the text that sed was using to replace relative to
absolute paths.

As a result sed was not effectively finding the text
"source ../include" to replace it, as the sed should be now
searching for ". ../include".

Similarly for "../Switches"
