Logical vs. bitwise AND in sbin/routed/parms.c

[Artem Belevich]

There's another case of '&' used improperly.

    if (hdr.elf.e_ident[EI_OSABI] & ELFOSABI_FREEBSD) {
         is_shlib = 1;
    } else {

hdr.elf.e_ident[EI_OSABI] is not a bitmask and '==' should've been used instead.
Now ldd.c has two instances of this bug due to copy/pasting of orignal code.
