[sysprof] build: add libsysprof-capture-2 static library

[Christian Hergert <chergert src gnome org>]

commit 469d54df5b4b067bbf84efeb7a67c578585b225f
Author: Christian Hergert <chergert redhat com>
Date:   Sat Jan 20 01:30:39 2018 -0800

    build: add libsysprof-capture-2 static library
    
    This allows external tooling to write capture files that Sysprof can open.
    Ideally, this will get used by GJS in the near future to implement profiler
    output for Sysprof.
