bpf: rename stack trace map operations

mauriciovasquezbernal · Alexei Starovoitov · commit 144991602e6a · 2018-10-19T13:24:30.000-07:00
In the following patches queue and stack maps (FIFO and LIFO
datastructures) will be implemented.  In order to avoid confusion and
a possible name clash rename stack_map_ops to stack_trace_map_ops
