[Buildroot] [git commit] package/doc-asciidoc.mk: unbreak docs logic after pkgdir change

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=bb4371d0863a2714e81b81bb2d5bafe18b4b3110
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Commit 748fc4be21e (package/pkg-utils.mk: remove trailing slash in pkgdir
definition) broke the docs generation logic:

make manual-html
>>>   Preparing the manual sources...
>>>   Generating HTML manual...
a2x: ERROR: missing ASCIIDOC_FILE: /home/peko/source/buildroot/output/build/docs/manual/manual.adoc

make: *** [docs/manual/manual.mk:12: /home/peko/source/buildroot/output/docs/manual/manual.html] Error 1

As it now ends up with the .adoc file one level below
(../docs/manual/manual/manual.adoc).  The reason is that the pkgdir macro is
used to define $(2)_DOCDIR, which is passed to rsync:

rsync -a docs/manual /home/peko/source/buildroot/output/build/docs/manual

Fix it by appending a / to the rsync arguments like we do elsewhere.
