shared/varlink: add missing terminator in json strings

Should finally fix oss-fuzz-14688.
8688c29b5aece49805a244676cba5bba0196f509 wasn't enough.

The buffer retrieved from memstream has the size that the same as the written
data. When we write do write(f, s, strlen(s)), then no terminating NUL is written,
and the buffer is not (necessarilly) a proper C string.
