Ensure that path defines are passed quoted to the compiler in order
to avoid cpp syntax errors.

The init script generated something like "DEVICE=/dev/sda" when it should
have been generating "DEVICE /dev/sda". mdadm errors on this. Patch by jow.

Also changed the default sendmail path to /usr/sbin/sendmail. No package
in LEDE provides /sbin/sendmail. msmtp provides /usr/sbin/sendmail so use
that.

Also add a patch to fix file paths for mdadm runtime files. mdadm currently
errors on them since /run is missing. Once /run is added to stock LEDE, this
patch can be removed.

Direct-IO support has to be enabled for the release build anyway, so
this hack is not worth keeping
