builtin/apply: tighten (dis)similarity index parsing
This was prompted by an incorrect warning issued by clang [1], and a
suggestion by Linus to restrict the range to check for values greater
than INT_MAX since these will give bogus output after casting to int.
In fact the (dis)similarity index is a percentage, so reject values
greater than 100.
