op-node: Adjust L1 Info Transaction Gas Parameters (#2582)

This reduces the gas on the L1 Info Transaction from 99,999,999
down to 75,000. This is required as the gas from deposits is now
being counted against the total gas used in the L2 block.

Typically the transaction only uses around 30k gas and 35k would
be fine; however, for the first transaction, it uses more gas to
set the storage slots from zero (around 70k gas). As such, we
set it to a single gas limit for the time being. We also give
it a buffer of 5k gas to ensure that this transaction will not
fail.
