tstest/iosdeps: update import list to mirror ipn-go-bridge

The purpose of this package is to test the iOS dependency closure, but
it had drifted from the actual import list of the ipn-go-bridge package
in the corp repo (the Go side of the iOS / macOS app).

Update the imports to match ipn-go-bridge's GOOS=ios import list,
adding many missing packages including wgengine/netstack,
feature/{taildrop,syspolicy,condregister}, the util/syspolicy/*
subpackages, types/{key,lazy,logid,netmap}, tsd, safesocket,
util/{eventbus,must,set}, and several net/* and ipn/* packages.

Drop two now-stale BadDeps entries (for now!): database/sql/driver and
github.com/google/uuid are reached via wgengine/netstack ->
github.com/prometheus-community/pro-bing, which netstack imports on
darwin || ios for ICMP user-ping, so the iOS app already ships them.
But we should fix that later.

Updates #19633
