memleak-bpfcc: AttributeError: type object 'BPF' has no attribute 'monotonic_time'

[Seth Arnold]

Hello, memleak-bpfcc fails on my Bionic system with:

$ sudo memleak-bpfcc
[sudo] password for sarnold:
Attaching to kernel allocators, Ctrl+C to quit.
[17:24:00] Top 10 stacks with outstanding allocations:
Traceback (most recent call last):
  File "/usr/sbin/memleak-bpfcc", line 513, in <module>
    print_outstanding()
  File "/usr/sbin/memleak-bpfcc", line 447, in print_outstanding
    if BPF.monotonic_time() - min_age_ns < info.timestamp_ns:
AttributeError: type object 'BPF' has no attribute 'monotonic_time'

Thanks
