useradd-staticids.bbclass: Fix for Bug 6633

When using the useradd-staticids.bbclass under meta/classes,
this error occurs:
"<username> - <username>: Username  does not have a static uid defined."
There was a problem with the regular expression for parsing parameters,
it was sometimes returning an empty string.

I have fixed this by skipping empty strings.
