[JENKINS-70622] Do not clean temporary files on agents (#24)

#11 was merged 5 years
ago but only released in 1.15 Feb 2023.  That change included a cleanup
step that removes specifically named files from the /tmp folder using
a Linux specific find command.  There is not enough benefit from that
cleanup step to justify the loss of portability to other Unix systems
like FreeBSD, OpenBSD, macOS, and Solaris.

https://issues.jenkins.io/browse/JENKINS-70622 reported the issue on
Solaris, AIX, and HP variants of Unix.
