binman: Skip processing "hash" subnodes of FIT subsections

Binman's FIT entry type can have image subentries with "hash" subnodes
intended to be processed by mkimage, but not binman. However, the Entry
class and any subclass that reuses its implementation tries to process
these unconditionally. This can lead to an error when boards specify
hash algorithms that binman doesn't support, but mkimage supports.

Let entries skip processing these "hash" subnodes based on an instance
variable, and set this instance variable for FIT subsections. Also
re-enable processing of calculated and missing properties of FIT entries
which was disabled to mitigate this issue.
