Use single instance of the identical INKERNEL() and PMC_IN_KERNEL()

macros on amd64 and i386.  Move the definition to machine/param.h.
kgdb defines INKERNEL() too, the conflict is resolved by renaming kgdb
version to PINKERNEL().

On i386, correct the lowest kernel address.  After the shared page was
introduced, USRSTACK no longer points to the last user address + 1 [*]
