intel-graphics-compiler: improve src package reproducibility

Improve the reproducibility of intel-graphics-compiler-src by replacing
the absolute build path with relative one in bison compiled files.
The --file-prefix-map could only work on bison 3.7 onward so add it only
when bison is newer than 3.7.

Also suppress #line directives in scanner that have the build path:
