perf probe: Show all cached probes
perf probe --list shows all cached probes when --cache is given. Each
caches are shown with on which binary that probed. E.g.:
-----
# perf probe --cache vfs_read \$params
# perf probe --cache -x /lib64/libc-2.17.so getaddrinfo \$params
# perf probe --cache --list
[kernel.kallsyms] (1466a0a250b5d0070c6d0f03c5fed30b237970a1):
vfs_read $params
/usr/lib64/libc-2.17.so (c31ffe7942bfd77b2fca8f9bd5709d387a86d3bc):
getaddrinfo $params
-----
Note that $params requires debuginfo.
