The following error was thrown when compiling `tools/perf` using OpenCSD
v0.11.1. This patch fixes said error.
```
CC util/intel-pt-decoder/intel-pt-log.o
CC util/cs-etm-decoder/cs-etm-decoder.o
util/cs-etm-decoder/cs-etm-decoder.c: In function
‘cs_etm_decoder__buffer_range’:
util/cs-etm-decoder/cs-etm-decoder.c:370:2: error: enumeration value
‘OCSD_INSTR_WFI_WFE’ not handled in switch [-Werror=switch-enum]
switch (elem->last_i_type) {
^~~~~~
CC util/intel-pt-decoder/intel-pt-decoder.o
cc1: all warnings being treated as errors
```
Because `OCSD_INSTR_WFI_WFE` case was added only in v0.11.0, the minimum
required OpenCSD library version for this patch is no longer v0.10.0.
