new approach for generating sysimport.c
...
(renamed to avoid any conflict with old p4 copies).
this approach doesn't require auto-generating
files also kept in p4, so it should be easier on
go users who don't sync very often.
this approach will be more work for go developers:
builtin.c needs to be copied to builtin.c.boot in p4
as new functions are added. mkbuiltin does this
for certain $USERs to help us remember.
