killall command fails with: no can_run function in Process.pm

Describe the bug

Running killall command on a FreeBSD server results in:

ERROR - Undefined subroutine &Rex::Commands::Process::can_run called

at /home/regular/perl5/perlbrew/perls/perl-5.36.0/lib/site_perl/5.36.0/Rex/Commands/Process.pm line 85.

killall is defined as follows:

sub killall {
  my ( $process, $sig ) = @_;
  $sig ||= "";

  if ( can_run("killall") ) {
    i_run( "killall $sig $process", fail_ok => 1 );
    if ( $? != 0 ) {
      die("Error killing $process");
    }
  }
  else {
    die("Can't execute killall.");
  }
}

Seems like there's no can_run function in Process.pm module.

Expected behavior

killing process by name successfully

How to reproduce it

Run the code example.

Code example

task "kill_top", sub {
  killall "top";
};

Additional context

I tested, and the same error occured locally on Debian Linux as well.

Rex version

1.13.4

Perl version

5.36.0

Operating system running rex

Debian

Operating system managed by rex

FreeBSD

How rex was installed?

cpan client

Start in Rex/Commands/Process.pm at the killall implementation and reproduce the reported failure with the provided task example. Verify that killall can execute successfully and terminate a named process on the reported environments.
