[PATCH] meta: build the linux-kernels cross libc-dev package if cross-profile is active

["'Tobias Schaffner' via isar-users" <isar-users@googlegroups.com>]

The linux-libc-dev-${DISTRO_ARCH}-cross package is not created when cross
building the kernel because the pkg.${BPN}.cross build profile is only
activated for -native builds with the :cross-pkgs override.

This is an issue for custom kernels, because without the custom cross package,
dependent packages fall back to the default linux-libc-dev, which may lack
custom kernel headers.

Ensure that the cross package is also build for cross-builds when
KERNEL_LIBC_DEV_DEPLOY=1 is set, by adding the pkg.${BPN}.cross profile to the
default BUILD_PROFILES.
