0156d6e2ba bpfloader: 4.19+ required error message "Android V" -> "Android U QPR2" 
This fixes up yesterday's commit that added
the error message in the first place.

Android U hopefully launches ~Sep/Oct 2023

Android U QPR1 should be approx. a quarter after that,
so ~Dec 2023 or ~Jan 2024.

Android U QPR2 presumably releases another quarter later,
ie. around March/April 2024.

Per: https://www.kernel.org/category/releases.html
The 4.14 LTS kernel series projected EOL is Jan, 2024

This means that U QPR1 is the last one that 'should'
still support 4.14.

We are free to drop support in U QPR2+ as those will
be released after 4.14 goes EOL.

aosp/main only merges into branches *after* the current
udc-qpr-dev and thus will not end up in U QPR1.

8a117a374b bpfLoader: automatically bump ringbuffer size up to page size 
A 4kB BPF_MAP_TYPE_RINGBUF does not work on 16kB page size kernel,
as an eBPF ring buffer size *must* be a multiple of the page size.

However, it is inefficient to force a 16kB RINGBUF on kernels
with only a 4kB page size.

It wastes 12kB of mlock'ed memory per ring buffer,
which isn't much, but - as we add more ringbuffers - it'll add up...

The userspace ring buffer code doesn't actually mind the
automatic increase in size, as it retrieves the actual
size from the map fd (ie. from the kernel) during init
and thus adjusts automatically.

e15e91ea0d remove inprocess tethering 
The logic dealing with in vs out-of-process tethering flags
was added in aosp/master once it was already not merging to tm-dev,
thus ending up only in udc-dev, it was later removed in aosp/master,
and then cherrypicked to udc-dev.

As such there is no shipping version of the bpfloader
(besides early U developer previews and betas)
with this requirement.

Ignore-AOSP-First: change must land in U first,
since it's not safe if it isn't approved for udc-dev
