Daniel Black 37c88445e3 mtr: use env for perl
On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or
elsewhere in the path.

Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to
find perl and run it.

#!/usr/bin/env perl
die <<EEE unless @ARGV;
Usage: $0 func1 [func2 [ ...] ]
This filter (stdin->stdout) removes lines from dbug trace that were generated
by specified functions and all functions down the call stack. Produces the
same effect as if the original source had DBUG_PUSH(""); right after
DBUG_ENTER() and DBUG_POP(); right before DBUG_RETURN in every such a function.
