[PATCH] perf test: Make perf trace enum augmentation tests exclusive

[PATCH] perf test: Make perf trace enum augmentation tests exclusive

[Thomas Richter]

Running both tests cases 'perf trace enum augmentation tests'
and 'perf trace BTF general tests' together causes the first test case
to fail:
 # for i in $(seq 5); do \
	./perf test 'perf trace enum augmentation tests' \
	'perf trace BTF general tests'; \
   done
 125: perf trace enum augmentation tests  : Ok
 126: perf trace BTF general tests        : FAILED!
 125: perf trace enum augmentation tests  : Ok
 126: perf trace BTF general tests        : FAILED!
 125: perf trace enum augmentation tests  : Ok
 126: perf trace BTF general tests        : FAILED!
 125: perf trace enum augmentation tests  : Ok
 126: perf trace BTF general tests        : FAILED!
 125: perf trace enum augmentation tests  : Ok
 126: perf trace BTF general tests        : FAILED!
 #

Test case perf trace enum augmentation tests' fails because  the second
test case 'perf trace BTF general tests' runs concurrently as can
be observed using a ps -ef | grep perf output list on a different
window. Both do a perf trace command concurrently.
Make test case 'perf trace enum augmentation tests' exclusive.

 # for i in $(seq 5); do \
	./perf test 'perf trace enum augmentation tests' \
	'perf trace BTF general tests'; \
   done
 125: perf trace BTF general tests        : Ok
 155: perf trace enum augmentation tests  : Ok
 125: perf trace BTF general tests        : Ok
 155: perf trace enum augmentation tests  : Ok
 125: perf trace BTF general tests        : Ok
 155: perf trace enum augmentation tests  : Ok
 125: perf trace BTF general tests        : Ok
 155: perf trace enum augmentation tests  : Ok
 125: perf trace BTF general tests        : Ok
 155: perf trace enum augmentation tests  : Ok
