systemd: fix dead link /var/log/README

There are 2 issues here:
First, in package systemd, there is a file /usr/lib/tmpfile.d/legacy.conf,
which will create a symlink to /usr/share/doc/systemd/README.logs during
boot time. But for oe, /usr/share/doc/systemd/README.logs is packaged in
systemd-doc, which will make /var/log/README is dead link.

Second, the symlink /var/log/README in legacy.conf use relative path:
"L /var/log/README - - - - ../../usr/share/doc/systemd/README.logs"
But for oe, when VOLATILE_LOG_DIR is true, /var/log is a link to
/var/volatile/log, so /var/log/README need link to
../../../usr/share/doc/systemd/README.logs, while VOLATILE_LOG_DIR is
false, /var/log is a dir, so /var/log/README need link to
../../usr/share/doc/systemd/README.logs. So current symlink in
legacy.conf will also make it a dead link when VOLATILE_LOG_DIR is true.

Turn off CREATE_LOG_DIRS to avoid these issues.
