apr: Update to 1.7.5

Full changelog of this release:

  *) SECURITY: CVE-2023-49582: Apache Portable Runtime (APR):
     Unexpected lax shared memory permissions (cve.mitre.org)
     Lax permissions set by the Apache Portable Runtime library on
     Unix platforms would allow local users read access to named
     shared memory segments, potentially revealing sensitive
     application data.
     This issue does not affect non-Unix platforms, or builds with
     APR_USE_SHMEM_SHMGET=1 (apr.h)
     Users are recommended to upgrade to APR version 1.7.5, which
     fixes this issue.
