    [CIFS-UTILS] Add another suggested package name for krb5 headers

    Added an alternate package name for krb5 headers.

    Noticed the following suggestion asks for the wrong package (at least
    wrong for FC17)

    checking krb5.h presence... no
    checking for krb5.h... no
    checking krb5/krb5.h usability... no
    checking krb5/krb5.h presence... no
    checking for krb5/krb5.h... no
    configure: WARNING: krb5.h not found, consider installing
    krb5-libs-devel. Disabling cifs.upcall.

    [sfrench at w500smf cifs-utils]$ sudo yum install krb5-libs-devel
    Loaded plugins: langpacks, presto, refresh-packagekit
    No package krb5-libs-devel available.
    Error: Nothing to do
    [sfrench at w500smf cifs-utils]$ sudo yum install krb5-devel

    (installing krb5-devel worked, but not krb5-libs-devel for this version)
