Bug RHEL #2000374
Bugs Upstream #24046, #25923

This patch provides 12-hour time for the English language UTF-8 locale as a
new locale en_US@ampm.UTF-8.

Two upstream commits were applied to en_US to create the new file en_US@ampm:
  Upstream commit: 7395f3a0efad9fc51bb54fa383ef6524702e0c49
  Upstream commit: 8cde977077b3568310c743b21a905ca9ab286724

en_US remains unchanged and the new file en_US@ampm is now supported.
