André Almeida 82f5ee35d0 scripts/kernel-doc: Fix build time warnings
As stated at Documentation/kbuild/llvm.rst, to make usage of ccache one
must set KBUILD_BUILD_TIMESTAMP=''. Setting this together with W=1
will trigger the following warning for every compiled file:

  date: invalid date ‘+%s’

This comes from kernel-doc script, that produces the following command
when KBUILD_BUILD_TIMESTAMP is empty:

  date -d"" +%s

That triggers the warning above. Add a space between the flag `-d` and
the string argument to fix date command and remove the warning.
