Remove systemd-bootchart

This commit rips out systemd-bootchart. It will be given a new home, outside
of the systemd repository. The code itself isn't actually specific to
systemd and can be used without systemd even, so let's put it somewhere
else.

-    <para>
-      <command>systemd-bootchart</command> is a tool, usually run at
-      system startup, that collects the CPU load, disk load, memory
-      usage, as well as per-process information from a running system.
-      Collected results are output as an SVG graph. Normally,
-      systemd-bootchart is invoked by the kernel by passing
-      <option>init=<filename>/usr/lib/systemd/systemd-bootchart</filename></option>
-      on the kernel command line. systemd-bootchart will then fork the
-      real init off to resume normal system startup, while monitoring
-      and logging startup information in the background.
-    </para>
-    <para>
-      After collecting a certain amount of data (usually 15–30
-      seconds, default 20 s) the logging stops and a graph is
-      generated from the logged information. This graph contains vital
-      clues as to which resources are being used, in which order, and
-      where possible problems exist in the startup sequence of the
-      system. It is essentially a more detailed version of the
-      <command>systemd-analyze plot</command> function.
-    </para>
-    <para>
-      Of course, bootchart can also be used at any moment in time to
-      collect and graph some data for an amount of time. It is
-      recommended to use the <option>--rel</option> switch in this
-      case.
-    </para>
-    <para>
-      Bootchart does not require root privileges, and will happily run
-      as a normal user.
-    </para>
-    <para>
-      Bootchart graphs are by default written time-stamped in
-      <filename>/run/log</filename> and saved to the journal with
-      <varname>MESSAGE_ID=9f26aa562cf440c2b16c773d0479b518</varname>.
-      Journal field <varname>BOOTCHART=</varname> contains the
-      bootchart in SVG format.

-    it more efficient and simpler. There are no longer any timing
-    issues with the data collector and the grapher, as the graphing
-    cannot be run until the data has been collected. Also, the data
-    kept in memory is reduced to the absolute minimum needed.</para>
