If an USDT probe is defined within a shared object, bpftrace expects the
path to that shared object instead of an executable. This means that we
need to replace __EXE__ in the bpftrace scripts differently, depending
on whether the application was linked statically or dynamically.
This is now done by the `scripts/bpf/gen.py` script. It lists all
available probes, along with their locations, of a process. Then, it
matches them to those described in a bpftrace script replacing the
__EXE__ markers with the listed location (either a path to the
executable or a shared library). If a bpftrace script uses a probe that
isn't listed, its __EXE__ will be replaced by a path to the executable.
