osmo-release.sh: Drop whitespace after = when parsing LIBVERSION

As a result whitespace ended up in some variables and then command
"expr" was not happy about it.
It was spotted because src/coding/Makefile.am had some whitespacing.
Since it's the only one, let's drop the whitespace there too to have
similar line in all Makefile.am files.
