Upgrade kernel to 4.14.341-openela

This is a continuation of the 4.14 series by the Open Enterprise Linux
Alliance, ostensibly to the same maintenance standards as the now
discontinued kernel.org LTS.

This code is primarily offered as a Git repository, with gz tarballs
also available, but no xz versions. Switching back to a gzipped version
of the kernel source code would introduce too much srcfs growth, so we
use the last kernel.org tar.xz release (4.14.336), and apply OpenELA's
changes using a patch generated from the Git repository.
