perf parse-events: Add bison --file-prefix-map option

During a perf build with O= bison stores full paths in generated files
and those paths are stored in resulting perf binary.

Starting from bison v3.7.1 those paths can be remapped by using the
--file-prefix-map option. Use this option if possible to make perf
binary more reproducible.
