kernel/elfcore.c: include proper prototypes

BugLink: https://bugs.launchpad.net/bugs/1848780

[ Upstream commit 0f749140 ]

When building with W=1, gcc properly complains that there's no prototypes:

  CC      kernel/elfcore.o
kernel/elfcore.c:7:17: warning: no previous prototype for 'elf_core_extra_phdrs' [-Wmissing-prototypes]
    7 | Elf_Half __weak elf_core_extra_phdrs(void)
      |                 ^~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:12:12: warning: no previous prototype for 'elf_core_write_extra_phdrs' [-Wmissing-prototypes]
   12 | int __weak elf_core_write_extra_phdrs(struct coredump_params *cprm, loff_t offset)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:17:12: warning: no previous prototype for 'elf_core_write_extra_data' [-Wmissing-prototypes]
   17 | int __weak elf_core_write_extra_data(struct coredump_params *cprm)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~
kernel/elfcore.c:22:15: warning: no previous prototype for 'elf_core_extra_data_size' [-Wmissing-prototypes]
   22 | size_t __weak elf_core_extra_data_size(void)
      |               ^~~~~~~~~~~~~~~~~~~~~~~~

Provide the include file so gcc is happy, and we don't have potential code drift
