genbuild_h: git builds: Make date(1) lang, locale, and timezone independent

Without that fix, when building from git, computers on
    different timezone will produce a different COREBOOT_BUILD
    and COREBOOT_COMPILE_TIME defines in the cbfs revision file.

For instance when building the following revision:
      d96669e9db mainboard/google/reef: Increase PL1 sampling period
    On a computer set to UTC, it will produce the following:
      #define COREBOOT_BUILD "Sat Feb 11 13:58:51 UTC 2017"
      #define COREBOOT_COMPILE_TIME "13:58:51"
    But with a computer set to CET, it will look different:
      #define COREBOOT_BUILD "Sat Feb 11 14:58:51 CET 2017"
      #define COREBOOT_COMPILE_TIME "14:58:51"
