[virt-tools-list] [virt-viewer] build-sys: Always prepend '-' to build id

[Christophe Fergeau]

When using the --with-buildid configure paramater, the build id which is
substituted in the MSI wxs file is automatically prepended by a '-', but
the build id which is used in the C files does not get this '-'
automatically.

Currently, the linux and mingw spec files prepend a '-' on their own to the
--with-buildid argument, but this causes the MSI installer to show 2 '-'
during installation: "Please wait while Windows configures VirtViewer
0.6.0--1"

This commit always prepends a '-' to the buildid strings, and removes the
'-' from the spec files. This is to ensure the separator between version
number and buildid is not forgotten, which could give a confusing version
number.
