build: fix logname systemd linkage

Browse Source 
Note there was worry about redundant linking with -lsystemd
when getlogin() is not replaced, however that is mitigated
in general with the --as-needed linker option (the lib-ignore
gnulib module). Tested with:

  ./configure --with-systemd gl_cv_func_getlogin_works=no

* NEWS: Mention the Build-related fix.

** Build-related
'logname' now builds, where getlogin() is replaced (e.g. with musl),
and systemd libs are being used, by linking the required libraries.
The multi-call binary built with configure --enable-single-binary is reduced
in size by around 10KB through the more efficient reuse of the 'test' code
by '[', and the 'true' code by 'false'.
