Remove build number in info.plist

[Raymond]

Hello.

The CFBundleShortVersionString in info.plist in the package is made with version and build number.
It's a problème for example with Munki because Munki import uses this key to build the Munki package and the build number break the process.

It's:
<key>CFBundleShortVersionString</key>
<string>3.5.4 :8b11d92d:</string>

It would be:
<key>CFBundleShortVersionString</key>
<string>3.5.4</string>
