introduce BPFLOADER_MAINLINE_U_QPR3_VERSION

Note: this is technically a little bit early,
as U QPR3 still runs netbpfload as 'system' uid by virtue of
netbpfload.33rc overriding 'service bpfloader',
but this will change in a followup, at which point U QPR3
will become special by virtue of always using mainline netbpfload

See: https://android.googlesource.com/platform/packages/modules/Connectivity/+/refs/heads/android14-qpr3-release/netbpfload/NetBpfLoad.cpp#262
