libelf: Check for mremap, elf_update needs it for ELF_C_RDWR_MMAP

Add a AC_CHECK_FUNCS configure check for mremap. Some systems like
KFreeBSD and the Hurd don't have it. Also add a configure warning
because without mremap elf_update will often fail when ELF_C_RDWR_MMAP
is used. ELF_C_RDWR_MMAP is an elfutils extension to libelf.
