Fix CMake extraction of sub architecture test

The length check is hard coded to the length of the string under test.
As the STRINGS match only filters out non printable characters, we've
no guarantee that the characters before the == position are printable
or not. So _pos may be > 1 and then string length check will be broken.

Replaced this by a pattern match to see whether there's something after
the ":".

Fixes: QTBUG-120125
Pick-to: 6.5 6.6 6.7
