Promote bcachefs-kmod from ::guru to ::gentoo with minor style
fixes. Thanks to Alexander Miroshnichenko for maintaining the package in
::guru.
As discussed with Alexander, they are welcome to contribute to the
package in ::gentoo even though not (yet) being a maintainer via proxy.
Also, as discussed in https://github.com/gentoo/gentoo/pull/45259 and
via PM with various parties, this does not merge the bcachefs-tools and
bcachefs-kmod packages, instead they are individual packages. If
experience tells us that it is problematic that bcachefs userland and
the kernel module are in separate packages then we can revise this.
Closes: https://github.com/gentoo/gentoo/pull/45259
