Documentation: Avoid creating man pages in source tree
Currently kernel-doc generates a dummy DocBook file when asked to
convert a C source file with no structured comments. For an
out-of-tree build (objtree != srctree), the title of the output file
is the absolute path name of the C source file, which later results
in a manual page being created alongside the C source file.
Change the title to be a relative path.
