7d2721ef7a fix(runtime-c-api) wasmer_last_error_message returns the length + 1.
Returning the error message's length + 1 mimics the
`wasmer_last_error_length` function that counts the trailing null
byte.

1d555301f7 feat(runtime-c-api) Check buffer size before creating the slice.
It's safer to check the buffer size is large enough to hold the error
message before creating the slice from raw parts.

Also, this patch remove the need for `last_error`, simplifying the
code a little bit. The `length` variable is casted to `usize` once.
