[PATCH] testsuite: Colon is reserved on Windows

["Torbjörn SVENSSON" <torbjorn.svensson@foss.st.com>]

The ':' is reserved in filenames on Windows.
Can't find any specification for this, but when there is no filename
defined in the map file, GCC will replace the ':' with a '-' in the
generated filename for the module.

Without this patch, the test case failes with:
.../ben-1_a.C:4:8: error: failed to write compiled module: Invalid argument
.../ben-1_a.C:4:8: note: compiled module file is 'partitions/module:import.mod'

gcc/testsuite:

	* g++.dg/modules/ben-1.map: Replace the colon with dash.
	* g++.dg/modules/ben-1_a.C: Likewise
