ci: pass alias key password to keytool keystore migration

The build-apk JKS->PKCS12 migration only supplied the store password,
so keytool prompted for the upload key's distinct password on the
non-interactive runner and failed with 'Too many failures - try later'.
Pass -srckeypass/-destkeypass ($KEY_PASSWORD) to match key.properties.
