[dpdk-stable] [PATCH] devtools: fix cleanup of temp file

[David Marchand]

The regexp part of the cleanup routine was not updated accordingly when
a common prefix for temp files was introduced.
Set the trap handler only when required.

Fixes: ff37ca5d3773 ("devtools: use a common prefix for temporary files")
