[LTP] [PATCH v1 1/2] syscalls/fstat{01,02}: rewrote testcases

[Christian Amann <camann@suse.com>]

Merged the two tests:
	fstat01 is a subset of fstat02 and is therefore not needed
	anymore.
Rewrote testcase:
	Cleaned up, ported to new library and added variants to test
	for libc aswell as the raw syscall.

- *
- *    OUTPUT SPECIFICATIONS
- *
- *    DURATION

- *
- *    DETAILED DESCRIPTION
- *	This is a Phase I test for the fstat(2) system call.  It is intended
- *	to provide a limited exposure of the system call, for now.  It
- *	should/will be extended when full functional tests are written for
- *	fstat(2).
- *
- *	Setup:
- *	  Setup signal handling.
- *	  Pause for SIGUSR1 if option specified.
- *
- *	Test:
- *	 Loop if the proper options are given.
- *	  Execute system call
- *	  Check return code, if system call failed (return=-1)
- *		Log the errno and Issue a FAIL message.
- *	  Otherwise, Issue a PASS message.
- *
- *	Cleanup:
- *	  Print errno log and/or timing stats if options given
- *
