[PATCH v2] include/wine/test.h: fix winetest_argv[1] in case of single test

[Eric Pouech]

Wine's test infrastructure allows to call ./wine <test>.exe without
test name when only a single test is available in <test>.exe.

Unfortunately, a lots of tests also rely on winetest_argv[1] to be
the name of current test
(esp. when respawning themselves to run sub processes).

So, ensure wintest_argv is correctly populated in the case of a <test>
containing a single test file and called without any argument on
command line.
