linux: replace host-python3 with BR2_PYTHON3_HOST_DEPENDENCY
Commit abce4a2b3 "linux: add BR2_LINUX_KERNEL_NEEDS_HOST_PYTHON3" [1]
introduced a Kernel dependency on host-python3.
Since the Kernel does not have any specific requirements on host
Python modules, or recent host Python version, this commit replaces
the host-python3 dependency with BR2_PYTHON3_HOST_DEPENDENCY. This
will skip the host-python3 compilation if a sufficient version (3.4 or
greater at the time of this commit) is already present on host. This
will save build time.
This optimization was suggested by Peter, in [2].
Note 1: this commit was checked to ensure that Kernel v6.10.9 arm64
defconfig (which does require a python3 interpreter to build) is
working with Python 3.4.
Note 2: BR2_PYTHON3_HOST_DEPENDENCY was introduced in commit b60729784
"support/dependencies: add a check for python3" [3].
