How to change temporary extract directory (default- /tmp) for Syslog-ng PE run installer

When using the run installer to install syslog-ng PE, it needs the /tmp/ directory with permission and storage to extract the files.
However, there could be some situations where the  /tmp/ directory does not have enough space or no access to the /tmp/ directory due to Linux system hardening. In this case, the installation will fail and will not proceed.

1st issue- No permission to /tmp/ directory:
 

Second issue- Not enough storage space on /tmp/ directory:

[root@XXXX ~]# ./syslog-ng-premium-edition-7.0.32.run -- -a --path /opt/apps --register -l "/root/152-794-940.txt"
Copying to a temporary location...
Creating directory zbs-1665661044-2547
Verifying archive integrity... All good.
Uncompressing syslog-ng-premium-edition
Not enough space left in . (2404 KB) to decompress /tmp/makeself.16887.240111203848.4579/makeself (390416 KB)

N/A

An alternative method to retry the installation is to change the temporary extract location from the default (/tmp/) to something else.

Example command to change and start the installation:

root@XXXX ~]# TMPDIR=/root/testemp/ ./syslog-ng-premium-edition-7.0.32.run -- -a --path /opt/syslog-ng --register

Here, TMPDIR is the variable to change the default extract location and extraction will happen on /root/testemp directory. So, declaring it before running the run the file will do the trick.

Please remember to to create the directory before as the run file will not create the directory.
