lib/functions.sh: ensure 32-bit wine directory is created

Set the WINEARCH environment variable to 'win32' so that wine will create
a 32-bit windows directory structure.  This is necessary on 64-bit
platforms since some 32-bit windows system dlls are installed into the
windows directory and the dlls must match the windows architecture and vice
versa.
