compress_doc.bbclass: support update-alternatives 

While doc file make use of update-alternatives to fix confliction,
we should reconfigure update-alternatives for doc compression.

Such as util-linux-doc:
...
update-alternatives --install /usr/share/man/man1/last.1 last.1
  /usr/share/man/man1/last.1.util-linux 100
...
was updated by doc_compress to
...
update-alternatives --install /usr/share/man/man1/last.1.bz2 last.1.bz2
  /usr/share/man/man1/last.1.util-linux.bz2 100
...
