sandbox: prevent segfault in tap_alloc()
Tap network interface initialization in sandbox
barebox leads to segfault under Debian Buster/Sid.
The problem is that strcpy(dev, ifr.ifr_name) inside
tap_alloc() tries to alter read-only data passed
by tap_probe() and barebox receives SIGSEGV.
Nobody uses network interface name returned
by tap_alloc() so we can drop this strcpy().
