build: bump ABI to sysprof-capture-4

GLib will now be linking against sysprof-capture-4.a. To support that,
sysprof had to remove the GLib dependency from sysprof-capture-4 which
had the side-effect of breaking ABi.

This bumps the dependency and includes a fallback to compile just the
libsysprof-capture-4.a using a subproject wrap.
