LU-2675 llapi: find_param cleanup part I

Add fp_ prefixes to several (dev,type,{u,g}id,{a,c,m}time,...,depth)
members of struct find_param. Remove the unused print_fmt
member. Remove the llapi internal arrays llapi_dir_filetype_table[]
and llapi_filetype_dir_table[] replacing their uses with IFTODT() and
DTTOIF().
