Subject: version.sh: Fix in-tree case and allow external variables
X-Git-Tag: v1.0.1~11

version.sh: Fix in-tree case and allow external variables

"$(basename $0)" would return the name of the script, when what is
needed is the name of the directory; use 'dirname' instead.
If PETITBOOT_VERSION is set, as in a buildroot environment, use this
variable instead of the default case.
