1. elf_reader: only read data from PROGBITS sections, ignore NOBITS …

   'Virtual' NOBITS sections like .bss always share an offset with another
   ELF section, but reading from them is expected to yield only NUL bytes.
   
   Prior to Go 1.18, opening a NOBITS section would yield a reader into
   the overlapping 'real' section, dutifully returning its non-NUL bytes
   and potentially reading past the end of the underlying file reader if
   the size of the NOBITS section was large enough. This was addressed in
   CL#375216.
   
   As both an optimization (in case of large .bss sections) and a workaround
   for this bug in Go versions 1.17 and earlier, only read data from PROGBITS
   sections, which all known LLVM versions use correctly. Return an error if
   a data section is not PROGBITS or NOBITS.
