[binutils/readelf] Fix printing of dwarf4 .debug_str_offsets.dwo
When compiling a hello world with dwarf4 split dwarf:
...
$ gcc -gdwarf-4 -gsplit-dwarf hello.c -save-temps -dA
...
we have in a-hello.s these three initial entries in .debug_str_offsets:
...
.section .debug_str_offsets.dwo,"e",@progbits
.4byte 0 // indexed string 0x0: short int
.4byte 0xa // indexed string 0x1: /home/vries/binutils
.4byte 0x1f // indexed string 0x2: main
...
but "readelf -ws a.out" starts at the third entry:
...
Contents of the .debug_str_offsets.dwo section (loaded from a-hello.dwo):
Length: 0x30
Index Offset [String]
0 00000000 main
...
This is a regression since commit 407115429b3 ("Modified changes for
split-dwarf and dwarf-5."), which introduced a variable
debug_str_offsets_hdr_len in display_debug_str_offsets.
Fix this by setting display_debug_str_offsets to 0 for the dwarf4 case.
