x86/boot: Drop sym_fs()

All remaining users of sym_fs() can trivially be switched to using sym_esi()
instead.  This is shorter to encode and faster to execute.

This removes the final uses of %fs during boot, which allows us to drop
BOOT_FS from the trampoline GDT, which drops an 16M arbitrary limit on Xen's
compiled size.
