[Libguestfs] Making the tests faster

[Richard W.M. Jones]

Currently 'make check' takes 23 minutes (at least) to run on my shiny
new laptop.  I'd like to make this faster because I spend a lot of
time waiting for them to finish, but first here's an analysis of time
spent now.

Build the test guests:
[only happens once, as long as you don't make clean]:

   tests/guests:       72 seconds

Test gnulib:

   gnulib:             13 seconds

Testing the API (about 12 minutes in total):

   tests/qemu:         13 seconds
   tests/c-api:       277
   tests/protocol:     16
   tests/disks:        90
   tests/mountable:    20
   tests/lvm:          10
   tests/luks:         53
   tests/md:           88
   tests/selinux:      13
   tests/ntfsclone:    10
   tests/rsync:        10
   tests/disk-labels:   4
   tests/hotplug:      20
   tests/nbd:          15
   tests/syslinux:     10
   tests/regressions:  62
   [tests/btrfs skipped by local configuration]
   [tests/mount-local skipped by local configuration]

Testing guestfish and bindings (about 6 minutes):

   fish:               70 seconds
   perl:               15
   ocaml:             190
   python:              5
   ruby:               10
   java:                5
   haskell:             4
   php:                 7
   erlang:             10
   lua:                29
   gobject:            10

Testing tools (about 5 minutes):

   align:              12 seconds
   cat:                40
   df:                 16
   edit:               27
   format:             17
   inspector:          19
   rescue:              4
   resize:             29
   sparsify:           69
   sysprep:            29
   tools:              17
   fuse:               20

Test environment:

   libguestfs 1.21.33
   libvirt 1.0.3 backend
   qemu 1.0.4
   Fedora 19
   Intel Core i7-3520M
