This package differs from Alpine's in two important ways:

* The script is in source= and installed, instead of created with a heredoc.

* There is no deinstall script to remove the certificate store.
  This is unnecessary, and violates APK's guarantee that user-generated
  content will not be modified.  We cannot control what users do inside the
  directory, and we cannot take ownership of the entire thing.  So we should
  not remove it.

Explicitly build scdaemon and the internal ccid driver, as well as
provide rules for udev.

If it is re-added later, pcscd should at least be run as an unpriv user
w/o any capabilities.

It's just a binary that's installed for testing purposes @ runtime. In
fact, we should investigate whether we want to install it at all.

Otherwise, we have -Wl,--as-needed passed to ld which it can't handle.
