py/makeqstrdefs.py: Fix handling GreenHills C/C++ preprocessor output.

The GreenHills preprocessor produces #line directives without a file name,
which the regular expression used to distiguish between
"# <number> file..." (GCC and similar) and "#line <number> file..."
(Microsoft C and similar) does not match, aborting processing.

Besides, the regular expression was unnecessarily wide, matching lines
containing a "#", followed by any  number of 'l','i','n', and 'e'
characters.
