CMake: Generate relative #line directives in qlalr output
When passing an absolute input file name to qlalr, the #line directives
in the output will contain absolute paths. For reproducible builds,
it's desirable to have relative paths.
Pass the input file as relative path to qlalr to produce relative #line
directives.
Fixes: QTBUG-96267
