[virt-tools-list] [virt-viewer v2 2/2] build-sys: Always prepend '-' to BUILDID

[Christophe Fergeau]

This was removed by commit 28a6bd6 as WINDOWS_PRODUCTVERSION
needs a buildid without a dash. Apart from this variable,
all other uses of buildid/BUILDID in virt-viewer source tree
need a dash between the version number and the buildid to avoid getting
output like "3.01" instead of "3.0-1"

Rather than patching every location where BUILDID is used, this commit
appends the "-" before substituting/defining BUILDID in configure.ac.
This does not modifies the buildid configure.ac variable, this way
WINDOWS_PRODUCTVERSION won't get an unwanted '-'.
---

New version of my previous attempt to achieve that which was breaking
WINDOWS_PRODUCTVERSION.
