mainline inclusion
from mainline-5.0-rc1
commit 1b3aae90c6abdf8a844da2aa4aed1eb6947a7d39
category: bugfix
bugzilla: NA
CVE: NA

-------------------------------------------------
This basically replicates what was done for 'perf report' in:

   b226a5a7 ("perf report: Allow user to specify path to kallsyms file")

This should help with resolving eBPF symbols, that are in kallsyms but,
of course, not in vmlinux.
