Fix udbParseLib.awk so it doesn't generate warnings with gawk.

Tested this change with both gawk and nawk and it worked fine.  If
the extra escape character is present and gawk is used, you'll get
warnings from gawk telling you it's ignoring the escape sequence
and just treating it as the character to begin with.
