Log:
fix early initialization of s390_host_hwcaps in LibVEX_FrontEnd

This is a follow-up to r3341 and r3344. r3341 split LibVEX_Translate into
LibVEX_FrontEnd and LibVEX_BackEnd. s390_host_hwcaps needs to be initialized
early when arch_host is VexArchS390X.

This also fixes none/tests/libvexmultiarch_test on MIPS64 BE platforms.
