makepkg: reorganize the restoration of settings by precedence
The extra variables on the commandline were inconsistently applied. They should override anything else, instead, most were overridden by environment variables with the exception of BUILDDIR (and this was not sanity-checked to see if it had write permissions). e.g. given the commandline: `PKGDEST="$(pwd)"` BUILDDIR="$(pwd)" makepkg PKGDEST=/doesnt/exist BUILDDIR=/doesnt/exist` We would incorrectly use the current working directory for PKGDEST. Meanwhile, we checked the wrong directory for BUILDDIR, and later errored when we tried to create $srcdir inside the non-writable directory "/doesnt/exist". In order to fix this, use the preferred bash builtin for saving variable definitions, similar to how we restore traps etc. rather than tediously redefining each one by hand, and restore this immediately after makepkg.conf is sourced. Finally, the `make`-style commandline overrides are applied. Also canonicalize_path is applied only on the final paths we try to use. While it is unlikely the value in makepkg.conf will be a relative path, since we now properly respect commandline overrides, they should be canonicalized as well.
