[patch] Dwarf section size fix when getbytesize is smaller than getFileSize

Hi,

This patch is to fix lldb freeze when getbytesize is smaller than getfilesize

When lldb is used to debug cygwin built executable on windows.

With more data read, .debugarrange handling function will loop forever

After it reads the gap between two sections, where is all zero filled.

Looks good.
