perf buildid-list: Add a "-m" option to show kernel and modules build-ids

This new option displays all of the information needed to do external
BuildID-based symbolization of kernel stack traces, such as those collected
by bpf_get_stackid().

For each kernel module plus the main kernel, it displays the BuildID,
the start and end virtual addresses of that module's text range (rounded
out to page boundaries), and the pathname of the module.

When run as a non-privileged user, the actual addresses of the modules'
text ranges are not available, so the tools displays "0, <text length>" for
kernel modules and "0, 0xffffffffffffffff" for the kernel itself.

Sample output:

  root# perf buildid-list -m

Committer notes:

u64 formatter should be PRIx64 for printing as hex numbers, fix this:
