inet.xml: fix invalid IPv4-mapped-address examples
* IPv6 address FFFF::192.168.42.2 is an invalid form as an IPv4-mapped address. This should be fixed as ::FFFF:192.168.42.2. The assigned address block is ::ffff:0:0/96. See RFC6890 Table 20 in the Section 2.2.2 for the further details. And for this IPv4-mapped address use *only*, the 32bit LSB of the IPv6 address can be written with the respective IPv4 address. See RFC4291 Section 2.2 Form 3 for the further details.
