oescripts: ignore whitespaces when comparing lines
list-packageconfig-flags.py determines the whitespace numbers according
to the longest package name. This is reasonable for the tool as it's
trying to generate pretty output.
However, in this selftest case, the output is hardcoded. This results in
"pinentry gtk2 libcap ncurses qt secret" not recognized
as correct as the expected line is:
"pinentry gtk2 libcap ncurses qt secret".
The difference is only about whitespaces. So we should ignore the whitespaces
when comparing lines.
