manually push option arguments to array instead of using s@

Browse source 
By mixing s@ for --$foo-hook options and manual pushing in --hook-dir,
it can happen that options get lost. Consider the following test:

use Getopt::Long;
my $arr = [];
GetOptions(
    'A=s@' => \$arr,
    'B=s' => sub { push @{$arr}, $_[1]; }
);
foreach my $hook (@{$arr}) { print "hook: $hook\n"; }

This works fine:

    perl test.pl --A=a1 --B=b1 --A=a2 --B=b2
    hook: a1
    hook: b1
    hook: a2
    hook: b2

This misses b1:

    perl test.pl --B=b1 --A=a2 --B=b2
    hook: a2
    hook: b2
