ipn/ipnlocal: add TS_FORCE_CACHE_NETMAP envknob to force netmap cachingapenwarr/aperture
Allow clients to force netmap caching via the TS_FORCE_CACHE_NETMAP
environment variable, bypassing the requirement for the control server
to grant the cache-network-maps node capability.
This is useful for tsnet users who want faster startup times via
cached netmaps but whose control plane doesn't grant the capability.
