Hello build bot (Jenkins),

flashrom: Convert do_read() into a libflashrom user

Aspire towards a goal of making cli_classic more of just
a user of libflashrom than having quasi-parallel paths in
flashrom.c

This converts the do_read() provider wrapper into a pure
libflashrom user. Also fix the case where the cli detects
a missing read() callback while the libflashrom interface
does not.

BUG=none
