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.

It looks like meson-0.56.2 has introduced a regression.

I've added "ln -sfv /bin/true /usr/bin/rsync" to chapter08/systemd.xml and am attempting another build to verify that things work.

In the meantime, rsync needs to be added to Required for systemd in BLFS. I'll also modify the dependencies in the appendix in LFS.
