[Buildroot] [PATCH v3 2/3] cryptodev: convert to new virtual package management.

[Eric Le Bihan]

The dependency check in 'cryptodev' has been updated to match the new
virtual package management.

Since this package is implemented via a choice rather than the usual
separate-package providers, BR2_PACKAGE_HAS_CRYPTODEV is always defined
when the 'cryptodev' package is selected.
