Bump Version to 1.5.2

Changes since 1.5.1:

• fail startup if pacemaker integration is disabled while SBD_SYNC_RESOURCE_STARTUP is conflicting (+ hint to overcome)
• improve logs
  • when logging state of SBD_PACEMAKER tell it is just that as this might still be overridden via cmdline options
  • log a warning if SBD_PACEMAKER is overridden by -P or -PP option
  • do not warn about startup syncing with pacemaker integration disabled
  • when watchdog-device is busy give a hint on who is hogging it
• improve build environment
  • have --with-runstatedir overrule --runstatedir
  • use new package name for pacemaker devel on opensuse
  • make config location configurable for man-page-creation
  • reverse alloc/de-alloc order to make gcc-12 static analysis happy
• improve test environment
  • have image-files in /dev/shm to assure they are in memory and sbd opening the files with O_SYNC doesn't trigger unnecessary syncs on a heavily loaded test-machine fallback to /tmp if /dev/shm doesn't exist
  • wrapping away libaio and usage of device-mapper for block-device simulation can now be passed into make via SBD_USE_DM & SBD_TRANSLATE_AIO
  • have variables that configure test-environment be printed out prior to running tests
  • finally assure we clean environment when interrupted by a signal (bash should have done it with just setting EXIT handler - but avoiding bashism might come handy one day)
