Fix the on-device installer after postmarketos-base-ui changes
Move the package back from aports to pmaports and fix fall out from postmarketos-base-ui related breakage:
- add the subset of depends from postmarketos-base-ui that are used in postmarketos-ondev
- upgrade to postmarketos-ondev 0.7.1, where I made it compatible with using the default tinydm config (not just the one overridden in postmarketos-base-ui-tinydm)
Reasoning for moving it from alpine to pmaports, in line with our new guidelines (that were written after the package was moved to aports):
- has postmarketOS branding
- enables services in post-install (similar to postmarketos-ui-* packages)

Important fix, right now the on-device installer is broken on edge. Merging as soon as CI passes.
