The sh script are harder to maintain for compatible different
xsh environment so convert it to python script
Also incorporate the fixes in
https://patchew.org/QEMU/20200929143654.518157-1-marcandre.lureau@redhat.com/

According to https://github.com/msys2/MSYS2-packages/issues/2176
We need use CYGWIN=noglob and MSYS=noglob in the environment variable
for disable wildcard expanding in msys or cygwin git, and setting the shell=False
