pool: Fix filtering of options in script HSM driver

Motivation:

The script HSM driver filters a number of options before calling the script as
these options are used internall by the driver. A regression in 2.13 broke this
filtering.

Modification:

When filtering on a map, we have to remember to filter on the key, not the entire
entry.

Result:

Fixed a regression introduced in 2.13 in which internal options like -c:puts were
erroneously included to the call out to the HSM script.
