ipc/sysctl: c/r fs.mqueue.msg_default fs.mqueue.msgsize_default
we already have 3/5 fs.mqueue.xxx sysctls so why not have all:
/proc/sys/fs/mqueue/msg_default is a read/write file for
setting/getting the default number of messages in a queue value
if attr parameter of mq_open(2) is NULL. If it exceed msg_max,
the default value is initialized msg_max.
/proc/sys/fs/mqueue/msgsize_default is a read/write file for
setting/getting the default message size value if attr parameter
of mq_open(2) is NULL. If it exceed msgsize_max, the default
value is initialized msgsize_max.
v2: remove check if kernel has sysctls as we do not support such an
old kernel(v3.5)
