[libvirt] [PATCH] docs/Makefile.am: remove unnecessary subshells

[Eric Blake]

* docs/Makefile.am (ChangeLog.html.in, %.html.tmp, %.html)
(html/index.html, $(devhelphtml)): Avoid spurious subshells.
---

I'm still having problems getting a VPATH build to work correctly,
but noticed this low-hanging fruit in the process.  Reformatting
to 80 columns is a nice side effect.
