package/musl: add upstream security fix for CVE-2020-28928

The wcsnrtombs function has been found to have multiple bugs in handling of
destination buffer size when limiting the input character count, which can
lead to infinite loop with no forward progress (no overflow) or writing past
the end of the destination buffer.
