testsuite: use SysprofProfiler for profiling
Instead of using sysprof-cli to profile subprocesses, this uses libsysprof's SysprofProfiler directly so that we can avoid an indirect subprocess as well as disabling the polkit nag. To do this, we have to link against libsysprof instead of libsysprof-capture. This is limited to the -Dbuild-tests=true and -Dprofiler=true case.
