Due to a copy-paste error when initially implementing this, it actually
uses a duplicate function name, usually resulting in lint_pkgbuild
overwriting the function definition.
Then the PKGBUILD lint gets run twice, one time before the PKGBUILD is
even sourced -- to potentially surprising results, like erroring out on
a pre-existing shell definition that doesn't match our expectations.
Seen in the wild with lint_config triggering an error for
'declare -x arch="foo"'
