Use specific Autoconf check for FS resize capability in libparted (#734718)

Browse source 
Replace Autoconf check for libparted >= 3.0

Currently uses a custom check which compiles an executable to check for
libparted version >= 3.0 to determine if the ped_file_system_resize()
function exists in the parted library.

Change to use a direct Autoconf check to determine the availability of
the ped_file_system_resize() function in the parted library.

Bug #734718 - Update Autoconf version specific libparted checks and
              defines to feature specific ones
