linux-user/elfload: Fix /proc/cpuinfo features: on s390x
elf_hwcap_str() takes a bit number, but compares it for equality with
the HWCAP_S390_* masks. This causes /proc/cpuinfo to display incorrect
hwcaps.
Fix by introducing the HWCAP_S390_NR_* constants and using them in
elf_hwcap_str() instead of the HWCAP_S390_*. While at it, add the
missing nnpa, pcimio and sie hwcaps from the latest kernel.
Output before:
features : esan3 zarch stfle msa
Output after:
features : esan3 zarch stfle msa ldisp eimm etf3eh highgprs vx vxe
