extract wine_test_dsp_files from C_SRCS variable

[Ilya Basin]

Looks like after this commit:
http://source.winehq.org/git/wine.git/?a=commit;h=6164ce2d820546ae5b26eb504bc108091c5679ea

the command
./tools/winapi/msvcmaker --no-wine
silently fails: only 'winetest.dsp' created

This patch should fix this
