[fixed-to-float.sh] Use float names for the GLES2 wrappers

Browse Source 
For example cogl_wrap_glFrustumx -> cogl_wrap_glFrustumf.

The wrappers get #defined to the float versions anyway but it helps
avoid some confusion.

The conversion is done using a regular expression in the upgrade
script. Some of the patches had to be updated to apply cleanly.
