opensc initrd hook requires dpkg-architecture

[Judd Tracy]

When adding smartcard support to unlocking a LUKS encrypted volume in initrd the update of initrd fails because the hook '/usr/share/initramfs-tools/hooks/cryptopensc' uses the command dpkg-architecture to determine the architecture of the libraries to copy into initrd. The package does not have a dependency(dpkg-dev) to install the package that contains dpkg-architecture.

I would also say that there really should not be a dependency on dpkg-dev for opensc either since it pulls in lots of development software that is not needed for most systems.

# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-4.15.0-76-generic
/usr/share/initramfs-tools/hooks/cryptopensc: 54: /usr/share/initramfs-tools/hooks/cryptopensc: dpkg-architecture: not found
E: /usr/share/initramfs-tools/hooks/cryptopensc failed with return 1.
update-initramfs: failed for /boot/initrd.img-4.15.0-76-generic with 1.

Thank you for your bug report, the package is coming from Debian so maybe you could also report the issue there?
