Make zuul_swift_upload.py more accurate for mime type detection

Browse Source 
When a text file is quite generic like a .css or .js file
libmagic will detect the file's content as text/plain. This
patch adds a check of the mime database in order to guess the
mime type given a file extension. This is only done
if text/plain is detected by libmagic.
