/var/tmp/frr is not being properly cleaned up

[donaldsharp]

Description

1 run of topotests creates almost 8k directories in the /var/tmp/frr directory:
root@eva:/var/tmp/frr# ls -altr | wc -l
7964
root@eva:/var/tmp/frr#

of which only 230 have files in them:

root@eva:/var/tmp/frr# find . -type f -print | wc -l
