adt-installer: Fix to work with meta-environment changes

There is a proper sysroot specified in the meta-environment script now,
which isn't a bad thing. We adjust the sed expression to cope with this.

That means the SDK installations in non-default paths start to work again.

Makedoc.sh uses home /tmp and fails is noexec is set

The Makedoc.sh script uses the following line to set TMPDIR

export TMPDIR=`mktemp -d ${TMPDIR:-/tmp}/ldt.XXXXXXXXXX`;

and then later in the script:

chmod u+x $TMPDIR/linuxdoc

Since TMPDIR is not set the script will default to /tmp and if /tmp
is set to noexec (which is becoming more common), the chmod call fails.
