Name "snippets" explicitly

Browse Source 
Earlier, this code was conceived of to test a "function" specifically,
but some future snippet could test multiple function calls, or a
subset of a function call (e.g. snippets/syscall_clock_gettime.c
already only tests one particular syscall diversion number).

Normalizing on the name "snippet" should make it easier to understand
the code going forward.
