hep: Store ipstr in a static buffer for exporting to cfg

When using hep(0x003) and hep(0x004) the extracted ip address
would be written to the local ipstr buffer but when returning
to the script the buffer would already be partially overwritten.

Keep the data around long enough by storing the result in a
static buffer.
