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().

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

/usr/include/limits.h uses the next_include directive
This was because of the -nostdinc
