[ADVAPI32] Fix copying the TokenSource string

Browse source 
TOKEN_SOURCE::SourceString is an 8 char non-null-terminated string. Copy it as such.

Fixes GCC 8 warning:
dll/win32/advapi32/misc/logon.c:638:5: error: 'strncpy' output truncated before terminating nul copying 8 bytes from a string of the same length [-Werror=stringop-truncation]
     strncpy(TokenSource.SourceName, "Advapi  ", sizeof(TokenSource.SourceName));
