LibJS: Remove read buffer overflow in Lexer::consume
The position is added to manually in the line terminator and Unicode
character cases. While it checks for EOF after doing so, the EOF check
used `!=` instead of `<`, meaning if the position went _over_ the
source length, it wouldn't think it was EOF and would cause read buffer
overflows.
For example, `0xea` followed by `0xfd` would cause this.
