systemd: upgrade 243.4 -> 244.1

Drop 0002-use-lnr-wrapper-instead-of-looking-for-relative-opti.patch a
variant on which was introduced in 2c1047310970 ("Upgrade to systemd
211+") in 2014. The oldest supported build machine is now CentOS 7 which
has --relative support in ln, so there no longer appears to be any need
for this change.

Rebase/refresh musl patches:

- replace missing.h with specific missing_... header
- fix additional WRITE_STRING_FILE_DISABLE_BUFFER
- fix more places that need netinet/if_ether.h
