Matthias Andree 8fe59c5847 lensfun: allocate buffers for AddMount()/AddCompat() large enough

...so that they can hold the terminating '\0' in C strings.

Found with clang's -fsanitize=address while debugging
RawTherapee 5.8 crashers.

Later found to be already fixed upstream here:
de954c9529

Not handed in for maintainer approval because obviously correct,
maintainer will be notified though.
