makepkg: use the `declare` builtin when backing up variables to eval

Rather than manually crafting foo_backup in a loop and eval'ing them
with a complicated escape pattern, store every splitpkg_overrides
element into a single variable via the eval-friendly `declare` builtin.

An alternative to eval would be using `printf -v` but this does not work
for arrays.

This has the additional benefit of reducing the number of
variables/arrays floating around in the environment.
