It's probably better to test for getprogname() instead of __APPLE__.

strncpy() always adds a terminating null byte.

vkd3d_get_program_name() is supposed to get just the name of the
executable, e.g. it needs to extract it from the full path. Our other
implementation also extracts the executable name when a program is run
under Wine. I'm afraid it might not be as simple as calling
getprogrname().

Moreover, in the long term it might not be necessary to have an
implementation of vkd3d_get_program_name() for programs running under
Wine. We'll probably start filling vkd3d_application_info in Wine
after the next vkd3d release.
