[OE-core] [PATCH 1/1] e2fsprogs/populate-extfs.sh: fix a problem on dash

[Robert Yang]

The dash can't handle the or [[ in parameter expansion, for example:

A=/usr/bin/[[
B=[[
C="${A%$B}"

The C should be "/usr/bin" in common, but it will be /usr/bin/[[ on
dash, use dirname to fix it.

NOTE:
There are 3 lines about parameter expansion, only fix the
DIR="${DIR%$TGT}" since the other 2 works will and are very useful in
this case.
