vfs: Force truncation even without permissions

O_TRUNC as a mode does not seem to imply write permissions
but we still wish to truncate the file before giving back a file
descriptor. Therefore the kernel can now override any permission checks
if it wishes to do a truncation while still using the "ordinary path".
