Gracefully handle bad octal literals

The code handling integer literals in dtc-lexer.l assumes that the flex
regexp means that strtoull() can't fail to interpret the string as a valid
integer (either decimal, octal, or hexadecimal).  This is not true for
octals.  For example '09' is accepted as a literal by the regexp,
strtoull() attempts to handle it as octal, but it has a bad digit.

This changes the code to give a more useful error in this case.
