Fix width of _stp_filename_lookup_5's offset to .debug_line_str

The read_pointer( ... DW_EH_PE_data4 ... ) gives a 4 byte value.
Elfutil's readelf.c does this with read_4ubyte_unaligned_inc().
Adjust the storage width for such offset to prevent overflow.
Problem demonstrated with context.exp / symfileline.tcl.
