Allocate enough shared string memory for stats of auxiliary processes.
This fixes a bug whereby the st_appname, st_clienthostname, and
st_activity_raw fields for auxiliary processes point beyond the end of
their respective shared memory segments. As a result, the application_name
of a backend might show up as the client hostname of an auxiliary process.
Backpatch to v10, where this bug was introduced, when the auxiliary
processes were added to the array.
