[edk2-libc Patch 1/1] AppPkg/Applications/Python/Python3.6.8: add support for atexit builtin module in py 3.6.8

["Jayaprakash, N" <n.jayaprakash@intel.com>]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3626

This commit adds support for the atexit a builtin module
in standard python 3.6.8 to it's UEFI port. There are tools
like Chipsec which are dependent on it but it can be used by
other python scripts running on UEFI shell with the help of
py 3.6.8 interpreter. Tested the changes on IA32 and X64 emulators
and it is working good.
