x86/boot: Fix build dependenices for reloc.c

c/s 201f852eaf added start_info.h and kconfig.h to reloc.c, but only updated
start_info.h in RELOC_DEPS.

This causes reloc.c to not be regenerated when Kconfig changes.  It is most
noticeable when enabling CONFIG_PVH and finding the resulting binary crash
early with:
