[LTP] [PATCH 1/2] request_key/request_key01.c: add new testcase

[Xiao Yang]

The testcase checks the basic functionality of the request_key(2).
request_key(2) asks the kernel to find a key which matches the
specified description. If successful, it attaches it to the nominated
keyring and returns its serial number.
