DocBook: Fix non-determinstic installation of duplicate man pages
Some kernel-doc sections are included in multiple DocBook files. This
means the mandocs target will generate the same manual page multiple
times with different metadata (author name/address and manual title,
taken from the including DocBook file). If it's invoked in a parallel
build, the output is non-determinstic.
Build the manual pages in a separate subdirectory per DocBook file,
then sort and de-duplicate when installing them (which is serialised).
