p8tool build sub-options for "--lua-minify" ("--keep-all-names" and "--keep-names-from-file=") are not applied
When used together with `p8tool build --lua-minify`, the sub-options `--keep-all-names` and `--keep-names-from-file=...` are ignored.

When used directly with `p8tool luamin` to minify a file already built, they do work. It's only when you build and minify at the same time that they are ignored.
