DnsResolver - improve api level detection for aosp

Use the maximum of ro.build.version.sdk & ro.product.first_api_level
to determine api level to use.

This makes AOSP master be >=R (technically already S) instead of ==Q.

See:                                        rvc-dev   aosp
  ro.build.version.sdk:                     [30]   vs [29]
  ro.product.first_api_level:               [29]   vs [31]
  ro.build.version.preview_sdk:             [0]    vs [1]
  ro.build.version.preview_sdk_fingerprint: [REL]  vs [...sha1...]

This does require us to treat aosp as the source of truth for netd,
but we do that anyway.
