libnet-1.2.x: fix musl compatiblity

The correct includes for musl are protected by an __GLIBC__ check in the
upstream sources.

Since musl does not provide own defines to identify itself, simply invert
the condition to !__UCLIBC__ in order to fix the build on all libc flavors
supported by OpenWrt.
