perf kmem: Pass additional arguments to 'perf record'

'perf kmem' has an input file option but current an output file option
fails:

  $ sudo perf kmem record -o /tmp/p.data sleep 1  
   Error: unknown switch `o'

  Usage: perf kmem [<options>] {record|stat}

     -f, --force           don't complain, do it
     -i, --input <file>    input file name
     -l, --line <num>      show n lines
     -s, --sort <key[,key2...]>
                           sort by keys: ptr, callsite, bytes, hit, pingpong, frag, page, order, mig>
     -v, --verbose         be more verbose (show symbol address, etc)
         --alloc           show per-allocation statistics
         --caller          show per-callsite statistics
         --live            Show live page stat
         --page            Analyze page allocator
         --raw-ip          show raw ip instead of symbol
         --slab            Analyze slab allocator
         --time <str>      Time span of interest (start,stop)

'perf sched' is similar in implementation and avoids the problem by
passing additional arguments to 'perf record'.

This change makes 'perf kmem' parse command line options consistently
with 'perf sched', although neither actually list that -o is a supported
option.
