[LTP] [PATCH] testcase: gethostid: Check if hostid is available

On some embedded systems, hostid may not be installed.
Because of that, the test will fail with:

gethostid01 1 TFAIL : gethostid01.c:171: fgets failed

The test should return a TCONF instead.
This commit uses tst_get_path function to check if "hostid"
is available in $PATH. Otherwise, it will return a TCONF.
