The xipfs configuration enabled CONFIG_NXFLAT and the nxflatxip example,
whose build runs mknxflat to generate the module thunk. The NXFLAT tools
are not installed in the CI container, so every CI build of this
configuration failed with "mknxflat: command not found".
* xipfs keeps the file system, the xipfs command and the test suite. It
builds with a plain toolchain, so CI still covers the file system code.
* xipfs-nxflat adds CONFIG_NXFLAT and CONFIG_EXAMPLES_NXFLATXIP and is
excluded from the CI build list, the same treatment the other NXFLAT
configurations already get (eagle100:nxflat, lm3s6965-ek:qemu-nxflat,
olimex-lpc1766stk:thttpd-nxflat).
Impact: CI and board configurations only. No source or runtime change.
