[Buildroot] [PATCH v2 2/2] package/frr: new package

[Vadim Kochan <vadim4j@gmail.com>]

FRR is free software that implements and manages various IPv4 and IPv6
routing protocols. It runs on nearly all distributions of Linux and BSD
as well as Solaris and supports all modern CPU architectures.

FRR currently supports the following protocols:

    BGP
    OSPFv2
    OSPFv3
    RIPv1
    RIPv2
    RIPng
    IS-IS
    PIM-SM/MSDP
    LDP
    BFD
    Babel
    PBR
    OpenFabric
    VRRP
    EIGRP (alpha)
    NHRP (alpha)

Some not-needed features were disabled to minimize package dependencies:

    - POSIX capabilities
    - RPKi
