[PATCH 3/3] selftests: vDSO: chacha: Provide default definition of HWCAP_S390_VXRS

[Thomas Weißschuh]

s390 does not provide a hwcap.h UAPI header.

Add an inline definition for the constant HWCAP_S390_VXRS until a proper
UAPI header is introduced.

Fixes: 210860e7f733 ("selftests: vDSO: check cpu caps before running chacha 
test")
