utils: sofprobeclient: fix musl build

alsa-project/tinycompress pull request #37 was opened from bkuhls:

With musl C library, we see following build failure:
```
probes_demux.c: In function ‘parser_parse_data’:
probes_demux.c:321:9: error: unknown type name ‘uint’; did you mean ‘int’?
  321 |         uint i = 0;

probes_demux.c:386:25: error: unknown type name ‘uint’; did you mean ‘int’?
  386 |                         uint data_to_copy;
```
uint is defined in <sys/types.h> header. It is usually included by <stdlib.h> but in musl stdlib.h doesn't include it.
