libproxmox-rs-perl ships /usr/share/perl5/PVE/RS/CalendarEvent.pm,
which was also present in libpve-rs-perl until version 0.5.1
This can lead to a (racy) issue while upgrading - depending
on which of libproxmox-rs-perl or libpve-rs-perl gets unpacked first
we potentially run into:
```
dpkg: error processing archive \
/tmp/apt-dpkg-install-lNBzMn/48-libproxmox-rs-perl_0.1.0_amd64.deb (--unpack):
trying to overwrite '/usr/share/perl5/PVE/RS/CalendarEvent.pm', \
which is also in package libpve-rs-perl 0.5.1
```
This patch follows the debian policy manual for these situations:
