doc: update SRCEXT/PKGEXT to reduce needlessly scary warnings

Currently this tells people that the settings should not be touched, but
we should just rely on the description of what it should be set to, and
leave it up to the user.  With the previous patch, makepkg aborts if an
invalid value is set, greatly reducing the danger of it being badly
configured.

Also make this clearer by indicating when it would be useful to change
the settings -- i.e. disable compression -- and ensure their described
defaults are based on the ones established during ./configure or meson
setup.
