[libvirt] [PATCH] build: use portable sed expressions

[Eric Blake]

* src/Makefile.am (libvirt.def, libvirt_qemu.def): '\}' and '\t'
are not required by POSIX.  Use '}' and literal tab instead.
(install-data-local): Avoid sed -i.
* tests/read-bufsiz: Likewise.
Reported by Mitchell Hashimoto.

This should work for you, but I'd appreciate positive feedback
from an actual build on OS X.

I used cp/rm rather than mv when replacing sed -i, so as to preserve
permissions on the just-installed file (in case creation of the
temporary file via > gets different permissions due to umask).

There was another use of sed -i in libvirt.spec.in, but as that
is specific to rpm building, where we know GNU sed will be in
use, I didn't see the point in changing it.
