Title: Drop vestigial `process.installPrefix`, `node --vars`, NODE_CFLAGS and NODE_PREFIX

Also removed unused node_config.h.in (replaced with config.gypi a while
back).

If/when this is pulled in, I can update to mention the dropped `process.installPrefix`.

Notes:
- process.installPrefix and `node --vars` worked in node 0.4.x.
- Not so in node 0.6.x (process.installPrefix is always undefined and `node --vars` prints nothing and exits 0.
- Given this behaviour in 0.6 I'm presuming it is okay to just yank them from the 0.8 release, rather than having some longer term official deprecation.
