perf probe: Use the last field name as the argument name

Set the last field name to the argument name when the argument
is refering a data-structure member.

e.g.
 ./perf probe --add 'vfs_read file->f_mode'
 Add new event:
   probe:vfs_read       (on vfs_read with f_mode=file->f_mode)

 This probe records file->f_mode, but the argument name becomes "f_mode".

This enables perf-trace command to parse trace event format correctly.
