util: copy_file_range() returns EBADF when used on a tty

Browse Source 
In nspawn we invoke copy_bytes() on a TTY fd. copy_file_range() returns EBADF
on a TTY and this error is considered fatal by copy_bytes() so far. Correct
that, so that nspawn's copy_bytes() operation works again.

This is a follow-up for a44202e98b.
