flashrom_tester: Drop dediprog, ec, and servo targets

None of these targets have been maintained or used for several years:

dediprog:
- Wasn't accepted by the argument filter in main.rs.

ec:
- Is incompatible with most tests because the EC only supports one
  protection range.

servo:
- Has been broken for >3 years because it uses the programmer string
  "ft2231_spi:type=servo-v2", where "ft2231" should be "ft2232".
