Subject: [PATCH] Do not disable buffering when writing to oom_score_adj

On musl, disabling buffering when writing to oom_score_adj will
cause the following error.

  Failed to adjust OOM setting: Invalid argument

This error appears for systemd-udevd.service and dbus.service.
This is because kernel receives '-' instead of the whole '-900'
if buffering is disabled.

This is libc implementation specific, as glibc does not have this issue.

Upstream-Status: Inappropriate [musl specific]
