[Qemu-trivial] [PULL 2/9] roms: Correct the EDK2_BASETOOLS_OPTFLAGS variable description

[Laurent Vivier <laurent@vivier.eu>]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

In commit 1cab464136b4 we incorrectly described the
EDK2_BASETOOLS_OPTFLAGS can pass CPPFLAGS and CFLAGS
options to the EDK2 build tools, but it only expands
the CFLAGS (not to the CPPFLAGS).
Update the description to be more accurate.
