[sanitizer] Pass -e dotbytes=10m to wget

[rprichard]

Summary

When wget writes to a log file, it defaults to 1KiB per dot, which
produces ~20000 lines of log output for the NDK. This "-e dotbytes"
syntax has existed since 1999 in wget.

This happens only once after clean build, so it did not annoy us, but I don't mind for even bigger value e.g. 10m

I suppose I'm OK with just 1m, unless you want it higher?
