cbootimage: disable on musl
cbootimage uses non-standard u_intXX_t types instead of the C99 types
uintXX_t types, which prevents it from building with the musl C library.
A patch to fix this has been submitted upstream, but since there are
many many occurences of such types, the patch is a bit large to carry in
Buildroot, especially compared to the fact that having this package
building against musl is probably not a top priority.
So for now, simply disable this package on musl, until upstream fixes
the issue and releases a new version.
