Fix SAA: set CWD=/usr/local/bin; include all SAA package binaries

- saa_dmi.go: set cmd.Dir=/usr/local/bin on all saa exec calls so
  acpica_bin/acpidump is found relative to correct working directory
- build.sh: copy all saa companion dirs (acpica_bin, ExternalData,
  tool, stunnel, GO_SNMP) to /usr/local/bin/ preserving structure
- iso/vendor: add acpica_bin/acpiexec, ExternalData/, tool/gpu/nVidia/x64/,
  tool/USBController/, stunnel/, GO_SNMP/ from SAA 1.5.0 release package
