[ofa-general] [PATCH] opensm: update OpenSM version according to the tree state

[Sasha Khapyorsky]

There is automatic OpenSM version (in generated osm_version.h file)
updater. It takes results from gen_ver.sh script, generated version has
form of:

* 3.1.8 , when tree state is equivalent to the opensm-3.1.8 release tag
* 3.1.8-4449c46 , same + git commit abbreviation, it is when the tree
                  is different from the release tag
* 3.1.8-4449c46-dirty, same as above, but the tree also has uncommitted
                       changes
