Rename the sections used for defining sandbox command line options so that they don't start with a '.'. ELF says that sections starting with a '.' are reserved for system use, but the sandbox runs as a normal user process so should be using user sections instead. Clang's ASAN adds redzones to non-user sections and the extra padding meant that the list of options was being corrupted. Naming the sections as user sections avoids this issue as clang handles them as we intended. Signed-off-by: Andrew Scull <ascull@google.com>
