Subject: tools: include reallocarray feature test in FEATURE_TESTS_BASIC
Patch-mainline: v4.19-rc1
Git-commit: db42a21a1e8d11a30a06050281c2723ec78b63a7
References: bsc#1109837

perf propagates its feature check results to libbpf.  This means
features for which perf probes must be a superset of libbpf's
required features.  perf depends on FEATURE_TESTS_BASIC for its list
of features.

commit 531b014e7a2f ("tools: bpf: make use of reallocarray") added
reallocarray use to libbpf, make perf also perform the reallocarray
feature check.

Fixes: 531b014e7a2f ("tools: bpf: make use of reallocarray")
