Hello David Wu, Edward O'Callaghan, Evan Benn, Hsuan Ting Chen, build bot (Jenkins),

flashrom_tester: Fix partial_lock_test on libflashrom

partial_lock_test (Lock_top_quad, Lock_bottom_quad, Lock_bottom_half,
and Lock_top_half) tries to:
1. Disable HWWP
2. Lock partial
3. Enable HWWP
4. Try to write the locked partial and expect a failure
...

The 4th step only works on flashrom binary since the binary will set
FLASHROM_FLAG_VERIFY_AFTER_WRITE=1 by default and it will error out
while verifying.

But libflashrom does not set any flag beforehand, so it has
FLASHROM_FLAG_VERIFY_AFTER_WRITE=0 and thus it will think the write
command works normally and raise no error. This causes the issue that
flashrom_tester with libflashrom has been failed until today.

To solve this issue, there are two solutions:
1. Take care of the default flags in libflashrom
2. Always pass --noverify to flashrom binary and verify it afterwards.

To make both methods more consistent, I fix it with approach 1.
