[OE-core] kernel-yocto.bbclass: Delete superfluous creation of ${S}/.git directory

[Robert P. J. Day]

In do_kernel_checkout(), replace the creation of ${S}/.git with just
the creation of ${S} since the .git subdirectory is created only a few
lines later using a "mv".  Here's the original code:

  rm -rf ${S}
  mkdir -p ${S}/.git

  echo "WARNING. ${WORKDIR}/git is not a bare clone."
  echo "Ensure that the SRC_URI includes the 'bareclone=1' option."

  # we can fix up the kernel repository, but at the least the meta
  # branch must be present. The machine branch may be created later.
  mv ${WORKDIR}/git/.git ${S}    <-- See?  There it is.

There's no functional change here, it's just less confusing.

  yes, i realize this doesn't change anything, but it's potentially
confusing for the code to explicitly create ${S}/.git, shortly before
it whomps over top of that directory anyway.  i spent a couple minutes
puzzling over the above trying to figure out if there was something
subtle happening i didn't understand.
