Allow colon in PXE bootfile URLs
- U-boot's PXE flow supports prefixing your bootfile name with an
IP address to fetch from a server other than the DHCP server,
e.g. `hostIPaddr:bootfilename`:
https://github.com/u-boot/u-boot/commit/a93907c43f847f076dd0e34ee3b69b5e8e6d0d29
- However, this breaks bootfile paths which contain a colon, e.g.
`f0:ad:4e:10:1b:87/7/pxelinux.cfg/default`
- This patch checks whether the `hostIPaddr` prefix is a valid
IP address before overriding the serverIP otherwise the whole
bootfile path is preserved
