Prefer linux/if_ether.h over netinet/if_ether.h if available since the
musl libc if_ether.h header does not allow mixing with kernel headers,
it will result in a struct ethhdr redefinition error.

Avoid using `union wait` under musl as it does not provide this definition.

- Include `sys/user.h` if `__WORDSIZE` is undefined
- Add `fcntl.h` to `libscc.c` in order to declare `loff_t`

Let configure include `sys/if_tun.h` when testing for `netinet/if_ether.h`
to detect the Kernel/libc header conflict on musl.
After this patch, configure will correctly detect `netinet/if_ether.h` as
unusable and the subsequent compilation will not attempt to use it.
Fixes the following compatibility error:

- Add missing `sys/ttydefaults.h` include to `config.c`
- Restrict usage of `error.h` to glibc and uclibc only
- Avoid including `linux/if_tun.h` on non-glibc/uclibc to prevent
musl kernel/libc header conflicts

Change occurences of `sys/unistd.h` to the standard `unistd.h` include.
Fixes build against musl.
Also refresh existing patch since it applied with fuzz.

The correct includes for musl are protected by an __GLIBC__ check in the
upstream sources.
Since musl does not provide own defines to identify itself, simply invert
the condition to !__UCLIBC__ in order to fix the build on all libc flavors
supported by OpenWrt.

Pass HAVE_RLIM_T via TARGET_CPPFLAGS since configure uses that define
but never actually declares it.
Without doing that, `config.h` tries to declare `rlim_t` itself which
leads to `config.h:126:16: error: 'long long long' is too long for GCC`
with musl on at least x86_64.
Also refresh patches while we're at it.

Under musl a compilation unit cannot include both linux/kernel.h
and sys/sysinfo.h at the same time since that leads to a redefinition
of `struct sysinfo`.
Change the autoconf template to include linux/kernel.h while testing
for sys/sysinfo.h to test for that conflict.
