Makefile: Abstract out "identify the pkgversion" code

Abstract out the "identify the pkgversion" code from the
rule for creating qemu-version.h, so it sets makefile
variables for QEMU_PKGVERSION and QEMU_FULL_VERSION.
(We will want to use these when building the Sphinx docs.)

NB: As we abstract this out, we use -e to check for .git
rather than -d, since in some situations .git may be a file
rather than a directory.
