Update ukm for modern perl

with perl 5.32.0 trying to use ukm gives:

```
$ ssh gitolite@localhost ukm
Enter passphrase for key '/home/kousu/.ssh/id_rsa':
FATAL: Can't use global $_ in "my" at /usr/lib/gitolite/commands/ukm line 296, near "($_"
Execution of /usr/lib/gitolite/commands/ukm aborted due to compilation errors.
```

This fixes it

```
$ ssh gitolite@localhost ukm list
Enter passphrase for key '/home/kousu/.ssh/id_rsa':
