added a signal handler to the tcheck_version to intercept the abort signal from H5check_version. Some systems would prints extra messages and/or core dump if the abort signal is not handled. This eliminates those unwanted side effect. Tested: h5committested.

* The default is to call the h5check_version() with the version information

* if it will indeed issue the warning message and aborts. With environment
