Title: compat: avoid unused warn with TEMP_FAILURE_RETRY

The version of TEMP_FAILURE_RETRY found on Linux has a GNU extension
that squashes the unused return value warning where applicable. This
adds a VOID_TEMP_FAILURE_RETRY to make the case explicit, casting the
expression value to void to avoid the warning.
