lib: Improve _parse_integer_fixup_radix base 16 detection
Base autodetection is failing for this case:
if test 257 -gt 3ae; then echo first; else echo second; fi
It is because base for 3ae is recognized by _parse_integer_fixup_radix() as
10. The code detects the first char which is not between 'a'/'A' or 'f'/'F'
to change base from dec to hex.
