Account for AWS-CI in Conditionals on CI Type

Several conditions exist in the scripts to see whether they're
running the On-Premises internal CI, or the TF.org CI.  They
all check (ultimately) the Jenkins URL as containing "arm.com"
or not.

This does not work with the addition of the AWS CI Jenkins,
whose URL ends in "aws.arm.com".  At least as a first step,
this patch changes those tests to look more specifically for
"oss.arm.com" rather than just "arm.com".

This at least seems unlikely to break any existing code, since
previously, Jenkins URLs ending in "arm.com" were always
preceded by "oss."
