commit: https://git.buildroot.net/buildroot/commit/?id=6fcdaa4c5096b51e16f295b0ba7939cc4db30f50
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

In order to run the full gamut of "perf tests" installing the perf
scripts is required, otherwise we run into errors similar to those:

	failed to open shell test directory: /usr/libexec/perf-core/tests/shell

Make this possible by introducing a new option allowing us to install
perf scripts.
