[pacman-dev] [PATCH] makepkg: use more schema.sh to clean the environment of special variables

[Eli Schwartz]

Fixes "arch" and "checkdepends" never having been unset, fixes b2sums
(but not ${!b2sums_@}) being recently left out.
The "build" function used to be unset as well, explicitly unset it as a
function and do the same for other official functions as well.
