Output warning in case changing the ownership of ubus' home
directory has failed. Besides, this avoids treating unused
result warning as error by GCC (with glibc-2.31, version 10.2):
procd-2020-12-12-7f12c89d/state.c: In function 'state_enter':
procd-2020-12-12-7f12c89d/state.c:147:4: error: ignoring
return value of 'chown' declared with attribute
'warn_unused_result' [-Werror=unused-result]
147 | chown(p->pw_dir, p->pw_uid, p->pw_gid);
