[PATCH] Get rid of do_shared_workdir task

[Ed Bartosh <ed.bartosh@linux.intel.com>]

Merged do_shared_workdir into kernel_do_compile

This change should fix race condition between do_compilemodules
and do_shared_workdir. Race occurs when do_compilemodules changes
include/generated/ directory content while do_shared_workdir
tries to copy it.

Fixes [YOCTO #7321]
