helpers: pmaports: Always fall back to parsing all APKBUILDS (MR 2476)

Previously, it would only fall back to parsing all APKBUILDs if a main
package was guessed for this potential subpackage. We do however want to
scan all APKBUILDs in case the package is provided by one of the
packages in pmaports.
