build: define NODE_EXPERIMENTAL_QUIC in mkcodecache and node_mksnapshot

Otherwise the build would fail with
`./configure --experimental-quic --ninja` as the list of per-Environment
values would not match and the code cache builder would not generate
code cache for the quic JS sources. This is more or less a band-aid -
a proper fix would be to aggregate these flags into something
that can be included by all these different binary targets.
