env: use dynamic memory management for DPDK 18.05.1+

Browse Source 
With all SPDK patches in place, we can now enable dynamic
memory management for all DPDK versions >= 18.05.1

Hugepages can be still reserved with [-s|--mem-size <size>]
option at application startup, but once we use them all up,
instead of failing user allocations with -ENOMEM, we'll try
to dynamically reserve even more. This allows starting DPDK
with `--mem-size 0` and using only as many hugepages as it
was actually necessary.
