[gnome-software] build: Bump sysprof dependency and allow building as a subproject

[Philip Withnall <pwithnall src gnome org>]

commit 9df47ee07299e2eb3e83d3d2abf33740ed0c40ab
Author: Philip Withnall <withnall endlessm com>

    build: Bump sysprof dependency and allow building as a subproject
    
    Bump the sysprof dependency to the new `libsysprof-capture-4.a`, which
    is what’s going to be maintained in future.
    
    Add subproject support, which will make the dependency management a bit
    easier while building, until the new version of sysprof is packaged
    widely.
