libdwfl: Special case core_file_read_eagerly for small ELF images.
Small ELF images, like linux-gate or linux-vdso, might be available in the
core file, but not on disk, even if we have a build-id. If the whole image
is small enough try to read them in from the core file to make sure symbols
and unwind information are always available for them. We would already map
them in if the core file was opened with ELF_C_READ_MMAP.
