tools/x86/kcpuid: Strip bitfield names leading/trailing whitespace

While parsing and saving bitfield names from the CSV file, an extra
leading space is copied verbatim.  That extra space is not a big issue
now, but further commits will add a new CSV file with much more padding
for the bitfield's name column.

Strip leading/trailing whitespaces while saving bitfield names.
