lvmpolld: fix `strerror_r` check for musl
We can't assume that strerror_r returns char* just because _GNU_SOURCE is
defined. We already call the appropriate autoconf test, so let's use its
result (STRERROR_R_CHAR_P).
Note that in configure, _GNU_SOURCE is always set, but we add a defined
guard just in case for futureproofing.
