Add option 'deterministic' for reproducible builds
Add the option 'deterministic' to make it easier to
achieve reproducible builds.
This option omits the {options,...} and {source,...} tuples in
M:module_info(compile), because those options may contain absolute
paths.
The author of ERL-310 suggested that only compiler options that
may contain absolute paths (such as {i,...}) should be excluded. But I
find it confusing to keep only some options.
Alternatives considered: Always omitting this information. Since this
information has been available for a long time, that would probably
break some workflows. As an example that some people care about
{source,...}, 2d785c07fbf9 made it possible to give a compiler option
to set {source,...}.
