posix04: add new "posix04" test
The dinning philosopher locking 'problem'. A given number of clients
try to lock on a file its own region and than the region 'right' from
its own region.

Print leading zeros after decimal point
The total time used for a test is a bit 'hard to read, because leading
zeros for the nsec part are missing, e.g.
total.tv_sec = 1
total.tv_nsec = 40013
results in
1.40013
instead of
1.

posix03: clean up and integrate into lockperf framework
Modify Rusty's original reproducer to run in a loop. Integrate it into
autoconf, and have it use the gnulib routines instead of its own
time_* ones. Add routines to clean up the children when the parent
exits. Switch to getopt() for option processing.
