fileinfo: Add G_FILE_ATTRIBUTE_FILESYSTEM_REMOTE attribute

Add filesystem attribute to detect remote filesystems in order to
replace hardcoded filesystem types in GtkFileSystem. Set this attribute
also for GLocalFile appropriately.

Bump version to 2.49.3, so that early adopters of new API have a version
number to target.
