UseSWIG: Fix handling of SWIG_MODULE_NAME source file property

Browse Source 
Fix a typo from commit 0bef9eb410 (UseSWIG: modernize module,
2018-01-29) that caused `UseSWIG` to ignore an eventually set property
`SWIG_MODLUE_NAME`.

Building multiple python modules using the mentioned property as
described in the docs could lead to an invalid, or even worse,
inconsistent `build.ninja` file.  The reason is that the generated list
of support files was not unique.  For each module the support file was
always named the same, namely `path/to/builddir/MODULENAME.py`.
