acpi: include PkgLength size only when requested
Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.
