Subject: test: checks for tracepoint tests

For testing the USDT tracepoint API in the functional tests we
require:
 - that we are on a Linux system*
 - that Bitcoin Core is compiled with tracepoints
 - that bcc and the the Python bcc module [0] is installed
 - that we run the tests with the required permissions**
otherwise we skip the tests.

*:  We currently only support tracepoints on Linux. Tracepoints are
    not compiled on other platforms.
**: Currently, we check for root permissions via getuid == 0. It's
    unclear if it's even possible to run the tests a non-root user
    with e.g. CAP_BPF, CAP_PERFMON, and access to /sys/kernel/debug/
    tracing/. Anyone running these tests as root should carefully
    review them first and then run them in a disposable VM.
