[IA64] Format /proc/pal/*/version_info correctly
/proc/pal/*/version_info is a bit confusing. HP firmware, at least,
reports 07.31 instead of 0.7.31. Also, the comment is out of place;
it's an internal detail about the implementation of ia64_pal_version.
Since the 2.2 revision of the SDM still states that PAL_VERSION can
be called in virtual mode, correct the comment to be more accurate.
