Move meminfo-writer to /usr/bin

[marmarek]

There it a tendency to merge /usr/bin and /usr/sbin (replace the latter
with a symlink). This caused a few issues already, including SELinux
mislabeling (QubesOS/qubes-issues#9663), file install issues where
%_sbindir RPM macro points at /usr/bin, and now on in-place upgrade
systemd unit points at /usr/sbin/meminfo-writer that doesn't exist at
the upgrade time.

Since this merging happened on Fedora 42 now, and much earlier on
Archlinux too, simplify things by simply moving meminfo-writer to
/usr/bin and don't have any special cases for distributions with merged
/usr/sbin or not. The change isn't relevant for Debian (yet?) but also
shouldn't hurt either.
