kbuild: Fix computing srcversion for modules
Recent change to fixdep:
commit b7bd182176960fdd139486cadb9962b39f8a2b50
Author: Michal Marek <mmarek@suse.cz>
Date: Thu Feb 17 15:13:54 2011 +0100
fixdep: Do not record dependency on the source file itself
changed the format of the *.cmd files without realizing that it is also
used by modpost. Put the path to the source file to the file back, in a
special variable, so that modpost sees all source files when calculating
srcversion for modules.
