[dpdk-dev] [PATCH] eal: fix directory permissions

[Adrien Mazarguil]

Executable bit must be set on directories for normal users to enter them.

This patch addresses the inability to start DPDK applications as non-root
due to errors such as:

 EAL: failed to bind /tmp/dpdk/rte/mp_socket: Permission denied

Fixes: 56236363b481 ("eal: add directory for runtime data")
