Subject: [PATCH 1/2] zfsdist: fix for python3

The BPF.get_kprobe_functions method tests if the passed argument
matches with a line of kallsyms, which is opened in binary mode.
Therefore the regex pattern must be bytes as well.

Subject: [PATCH 2/2] make tcpdrop and zfsslower python3 compatible (#1817)

Make the input string of get_kprobe_functions as
bytes literal in tcpdrop and zfsslower so the
tool can be python3 compatible.

Signed-off-by: Yonghong Song <yhs@fb.com>
(cherry picked from commit 3b86b565d3a416a250772bd6bf4ea282bd856fe9)

NOTE:
  * The fix for tools/tcpdrop.py is dropped since the script doesn't
    exist in 0.5.0.
