QRTR dependency in tqftpserv and pd-mapper

Currently the init.d scripts for tqftpserv and pd-mapper both depend on the qrtr service, however the APKBUILDs don't reflect this dependency, leaving it up to device / soc packages to depend on qrtr.

QRTR has also been upstreamed into the mainline kernel, meaning for mainline devices the userspace daemon is actually not needed at all.

Modifying the init.d scripts for tqftpserv and pd-mapper to remove the dependency will resolve the issue by allowing the services to start.

Perhaps we could create -mainline versions of tqftpserv and pd-mapper which don't depend on qrtr, and amend the APKBUILDS of the current versions. They could also be added as dependencies to the msm-modem downstream/mainline subpackages, or to a new metapackage to simplify any device packages that depend on them.

Alternatively, as QRTR will just idle on mainline devices with CONFIG_QRTR enabled, it would probably be fine to just fix the dependencies and leave it in for all devices.
