glusterfsd/main: fix OOM adjustment for older kernels
Milind Changire reported that GlusterFS fails to build on RHEL5
because linux/oom.h is unavailable.
Milind's initial patch disables OOM adjustment completely
for those environments that do not have this header. However,
I'd take another approach that:
1) checks for linux/oom.h in compile-time and defines necessary
constants if the header is not present;
2) checks for available OOM API in /proc in run-time and uses it
accordingly.
This allows OOM to be adjusted properly on RHEL5 (the kernel is pretty new
to present /proc API for that) as well as RHEL6 (the kernel has many thing
backported including new /proc API).
