    kdump-lib: Drop 'file' dependency in is_uki

    The 'file' utility is no longer installed per default. In addition there
    was an update to it so it now reports the file type as
    application/vnd.microsoft.portable-executable. Thus fall back to use
    objdump to avoid adding yet an other dependency for kdump-utils and deal
    with different versions of 'file'.

    Note: This has the small drawback that objdump is arch specific. I.e.
    examining a aarch64 UKI on a x86_64 machine will return an 'file format
    not recognized' error.
