Fix UEFI record regex

I accidently put colons on the test data and remembered taking the
colon character out of the regex I was working on, but apparently
left it in, and accounted for the active entry indicator flag
which appears to have inconsistent support across vendors.

The regex has been fixed, and a test added from a Lenovo SR650
which has some additional string entry data in the UEFI output
which may separate entries.
