meminfo_numa: fix crash on CentOS 6 kernel

It turns out, on some kernels (notably - CentOS6) there is an empty line
inserted at the beginning of /sys/devices/system/node/node*/meminfo
files.  The leads to node_exporter crash on such kernels.

Fix this by checking for empty string first.

Add new per NUMA node memory statistics collector

It is sometimes useful to understand the distribution of free/occupied
memory between NUMA nodes to deal with performance problems. To do so,
add new meminfo_numa collector that enables exporting of per node
statistics along with unit and end-to-end tests for it.
