Currently NETNS_RUN_DIR is hardcoded and refers to /var/run/netns.
However, some systems (e.g. Android) doesn't have /var
which results in error attempts to create network namespaces on these
systems. This change makes NETNS_RUN_DIR configurable at build time
by allowing to pass environment variable to make command.
Also, this change makes /etc/netns directory configurable through
NETNS_ETC_DIR environment variable.
For example: ./configure && NETNS_RUN_DIR=/mnt/vendor/netns make
Tested: verified that iproute2 with configuration mentioned above
creates namespaces in /mnt/vendor/netns
