build: avoid errors during release candidate kernel packaging
The build system allows to use Linux release candidate kernels (-rcX).
For this a target/linux/generic/kernel-6.XY as follows is needed:
LINUX_VERSION-6.XY = -rc1
LINUX_KERNEL_HASH-6.XY-rc1 = 18ba6ebd72f46b881e0d73e390b2888b7b43...
Sadly the builds fail with a packaging error.

mkpkg --info "name:kernel" --info "version:6.15-rc1~c4bf...1f6-r1"
ERROR: info field 'version' has invalid value: package version is invalid
The apk metadata specification reads:
"... Currently the APK version specification is as follows:
number{.number}...{letter}{_suffix{number}}...{~hash}{-r#} ...
Optionally one or more _suffix{number} components can follow.
The list of valid suffixes (and their sorting order) is: alpha,
beta, pre, rc, <no suffix>, cvs, svn, git, hg, p."
Given that the kernel uses "-rcX" naming scheme and apk requires
"_rcX" instead, simply translate the dash to an underscore for
these builds.
