tests fdleak.h close all open file descriptors > 2

Use sysconf (_SC_OPEN_MAX) to find the upper limit. Or use 1024
if that fails.

Tested with:

 #include 
 #include 
 int main (int argc, char *const argv[])
 {
   for (int i = 0; i < 100; ++i)
 dup (1);
   execvp (argv[1], argv + 1);
   exit (1);
 }

gcc -o dup100 dup100.c

./dup100 valgrind --track-fds=yes /bin/true
 ==673839== FILE DESCRIPTORS: 103 open (3 std) at exit.
 ==673839== Open file descriptor 102: /dev/pts/5
 ==673839==
 [...]

 ./dup100 perl tests/vg_regtest none/tests/fdleak*vgtest
all fail
 with patch all succeed
\o/
