gprofng: read Dwarf 5

gprofng reads Dwarf to find function names, sources, and line numbers.
gprofng skips other debug information.
I fixed three places in gprofng Dwarf reader:
 - parsing the compilation unit header.
 - parsing the line number table header.
 - parsing new DW_FORMs.

Tested on aarch64-linux/x86_64-linux.
