[musl] [PATCH] dynlink: fix get_lfs64() with posix_fallocate64

[Florian Ziesche <florian.ziesche@gmail.com>]

Hi,

this patch increases the buffer size by one in get_lfs64() so that it
works with posix_fallocate64.
"posix_fallocate64" is 17 characters long, so 16 is one too short.

Simplified example:
