Fix systemd to build with Linux-API-Headers-5.11.14 and higher

[Douglas R. Reno]

As John Burrell reported here ( ​https://lists.linuxfromscratch.org/sympa/arc/lfs-dev/2021-04/msg00000.html ), the systemd build will fail with Linux-API-Headers-5.11.14 and higher. This seems to be due to a change in the RFKILL API.

The exact error message is:

FAILED: systemd-rfkill.p/src_rfkill_rfkill.c.o

and then:

../src/rfkill/rfkill.c:339:23: warning: comparison of integer
expressions of different signedness: ‘ssize_t’ {aka ‘long int’} and
‘long unsigned int’ [-Wsign-compare]
339 | if (l < RFKILL_EVENT_SIZE_V1)
| ^

[-Werror=format=]
340 | return
log_error_errno(SYNTHETIC_ERRNO(EIO), "Short read of struct
rfkill_event: (%zd < %d)",

and finally:

cc1: some warnings being treated as errors

ninja: build stopped: subcommand failed.

As Xi mentioned, the patch will need to be applied for 248 as well.

I'm going to get a patch for 247 going using the following commit: ​https://github.com/systemd/systemd/commit/ab1aa6368a883bce88e3162fee2bea14aacedf23 - when we go to 248, I will do the same.
