sh: Remove setting variables from dotcmd/exportcmd.
It is already done by evalcommand(), unless special-ness has been removed,
in which case variable assignments should not persist. (These are currently
always special builtins, but this will change later: command builtin,
command substitution.)
This also fixes a memory leak when calling . with variable assignments.
Example:
valgrind --leak-check=full sh -c 'x=1 . /dev/null; x=2'
