apr: remove -std=gnu23 from apr_rules.mk to fix reproducibility

With the updated ax_prog_cc_for_build.m4 from
apr: fix build with autoconf-2.73
it now correctly detects -std=gnu23 usability on host gcc and doesn't
try to use it e.g. with gcc-13 which doesn't support it, but that causes
build reproducibility issue between builds on such hosts as
CC_FOR_BUILD is included in installed /usr/share/build-1/apr_rules.mk
