Add support for text/vCard and text/vCalendar MIME type

A vcf file can alias to both "text/vCard" and "text/x-vCard" MIME
types and an ics file can alias to "text/vCalendar" as well as
"text/x-vCalendar". However, if LineageOS does not get the "x-"
MIME type, it will incorrectly display an empty MMS.
