tests/qtest: i440fx-test: Rewrite create_blob_file() to be portable

Browse Source 
Previously request_{bios, pflash} cases were skipped on win32, mainly
due to create_blob_file() calling mmap() which does not exist on win32.
This rewirtes create_blob_file() to be portable, so that we can enable
these cases on Windows.
