dtc: Fix error reporting in push_input_file()

Browse Source 
Error reporting in push_input_file() is a mess.  One error results in
a message and exit(1), others result in a message and return 0 - which
is turned into an exit(1) at one callsite.  The other callsite doesn't
check errors, but probably should.  One of the error conditions gives
a message, but can only be the result of an internal programming
error, not a user error.

So.  Clean that up by making push_input_file() a void function, using
die() to report errors and quit.
