package/iptables: nfsynproxy not available on musl

utils/nfsynproxy.c needs several TCP_* constants which are not yet
provided by musl, they were added Jan 17, 2016 to musl:
http://git.musl-libc.org/cgit/musl/commit/?id=53f41fb568ae43034c9876cc9bd3961fd6d13671

Until we support a musl version containing the constants we disable
the option for building nfsynproxy on musl.
