4bc5353c92 scripts: Specify the stats to take into account 
There are many more stats on buildstats that 'Elapsed time', so make the script
more flexible to support all stats. Some cmd line examples:

$ buildstats.sh -s 'utime'

Buildstats' data covers proc's stats in different areas, including CPU times,
IO, program system resources and child program system resources. In order
to print values on each of these sets from command line, one can use the
following:

$ buildstats.sh -H -s 'TIME' | less

$ buildstats.sh -H -s 'IO' | less

and 'RUSAGE' and 'CHILD_RUSAGE' for program and program's child system
resources.

f0af24eedf buildstats: Outputs 'task recipe elapsed-time' from each buildstats' recipe 
Given a 'buildstats' path (created by bitbake when setting
USER_CLASSES ?= "buildstats" on local.conf) and task names, outputs
'<task> <recipe> <elapsed time>' for all recipes. Elapsed times are in
seconds, and task should be given without the 'do_' prefix.

Some useful pipelines

1. Tasks with largest elapsed times

    $ buildstats.sh -b <buildstats> | sort -k3 -n -r | head
    do_compile perl-5.20.0-r1 221.82
    do_configure gettext-native-0.19.4-r0 140.34
    do_compile openssl-native-1.0.2a-r0 107.48
    do_compile openssl-1.0.2a-r0 102.10
    do_configure perl-native-5.20.0-r0 90.70
    do_configure gettext-0.19.4-r0 88.17
    do_compile gcc-cross-i586-4.9.2-r0 83.98
    do_configure m4-native-1.4.17-r0 83.44
    do_compile qemu-native-2.2.0-r1 71.69
    do_compile glibc-2.21-r0 60.88

2. Min, max, sum per task

    $ buildstats.sh | datamash -t' ' -g1 min 3 max 3 sum 3 | sort -k4 -n -r
    do_configure 0.03 140.34 1968.66
    do_compile 0.01 221.82 1664.44
    do_install 0.03 40.31 330.45
    do_populate_sysroot 0.11 34.45 229.23
    do_unpack 0.01 36.1 193.54
    do_patch 0.01 9.2 62.07
    do_fetch 0.01 6.66 32.13
    do_populate_lic 0.09 1.65 30.7
