Subject: [PATCH net 4/6] tools: bpftool: remove spurious line break from error message

From: Quentin Monnet <quentin.monnet@...ronome.com>

The end-of-line character inside the string would break JSON compliance.
Remove it, `p_err()` already adds a '\n' character for plain output
anyway.

Fixes: 9a5ab8bf1d6d ("tools: bpftool: turn err() and info() macros into functions")
