Canonicalize the use of SRC_BASE to fix INDEX and duds builds on head

nodes that don't have /usr/src.  On pointyhat, this "just happens to
work"; on a cleanly installed system like pointyhat-west, it didn't.

Add overrides for Linux compatibility (again, it "just happened to work"
on pointyhat).

Move the code that sets PORTSDIR and SRC_BASE to the server side only.
The code that overrides OSVERSION, OSREL, and BRANCH _must_ remain in
the common code.
