leaking_addresses: cache architecture name
Currently we are repeatedly calling `uname -m`. This is causing the
script to take a long time to run (more than 10 seconds to parse
/proc/kallsyms). We can use Perl state variables to cache the result of
the first call to `uname -m`. With this change in place the script
scans the whole kernel in under a minute.
Cache machine architecture in state variable.
