Tobias Schmidt 515b5a933d Fix build tags of loadavg collector
The collector is only implemented for a subset of all operating systems
supported by go. Compilation will fail if attempted for another OS
target.

Kevin Pettijohn d2fbeeb3c3 Added loadavg collector for solaris
It seems solaris prefers "sys/loadavg.h" over "stdlib.h" when
fetching the load average.

For Illumos based OSes it was required to include "sys/time.h" to
ensure that "hrtime_t" was defined.

It also required setting the ldflags "-fno-stack-protector -lssp" to
avoid undefined symbols when linking with gcc.
