x86: make crashdump works

1. KERNEL_CRASH_DUMP should depends on KERNEL_PROC_KCORE (kexec use it)
2. select crashkernel mem size by totalmem
   mem <= 256M disable crashkernel by default
   mem >= 4G use 256M for crashkernel
   mem >= 8G use 512M for crashkernel
   default use 128M
3. set BOOT_IMAGE in kdump.init
4. resolve a "Unhandled rela relocation: R_X86_64_PLT32" error

Tested on x86_64
