exewrapper: report name of failed DLL in error message
This uses C string literal concatenation.
Example output:
$ hg version
abort: failed to load Python DLL python27.dll
Note that HGPYTHONLIB does not contain the trailing .dll, which works here
because the documentation of LoadLibrary [1] says, that if no file name
extension is specified in the filename parameter, the default library
extension .dll is appended.
See [2] for a motivation of this change.
