[PATCH v5 7/7] string: Implement strstarts() with strprefix()

[Alejandro Colomar <alx@kernel.org>]

[-- Attachment #1: Type: text/plain, Size: 863 bytes --]

The compiler should be able to optimize out the unused pointer
arithmetic done at the end, so performance-wise this shouldn't change
anything.

This change de-duplicates the almost-identical implementations,
and better shows the relationship between the two functions.
