Slight simplification of copyuvm. We could simplify other things now that processes are contiguous, but we'd have to think harder about the error paths.

no more pminit, or ELF header at 0x10000
kinit() knows about end and PHYSTOP
map all of kernel read/write (rather than r/o instructions)

set only PG and WP in vminit; the rest don't seem to be needed and are confusing

(maybe this never worked, but it works now)
