build-sys: fix crlf-ending C code

Browse Source 
On msys2, the shader-to-C script produces bad C:
./ui/shader/texture-blit-vert.h:2:5: error: missing terminating " character [-Werror]

Fix it by changing the line ending from crlf to lf, and convert the
script to Python (qemu build seems perl-free after that).
