tests: Use free rather than TPM_Free (OS/X)

Use free rather than TPM_Free to avoid the following warning:

tpm2_setprofile.c:377:18: warning: passing 'char *' to parameter \
  of type 'unsigned char *' converts between pointers to integer \
  types with different sign [-Wpointer-sign]

        TPM_Free(profile);

../include/libtpms/tpm_memory.h:57:36: note: passing argument to \
  parameter 'buffer' here

void       TPM_Free(unsigned char *buffer);
