x86: fix lguest build failure
drivers/lguest/x86/switcher_32.S:(.text+0x3815f8): undefined reference to `LGUEST_PAGES_regs_trapnum' This problem was caused by asm-offsets.c only having the offsets when lguest *guest* support was set, not lguest host (host support used to imply guest support, so now they're separate these bugs come out). Lguest guest support and host support are separate config options: they used to be tied together. Sort out which parts of asm-offsets are needed for Guest and Host.
