Subject: [PATCH] interval.h: add missing header

The ssize_t type requires the unistd.h header. This fixes build with musl
libc:

In file included from ../include/tinyalsa/limits.h:32:0,
                 from limits.c:1:
../include/tinyalsa/interval.h:38:2: error: unknown type name 'ssize_t'
  ssize_t max;
  ^
