[yocto] do pkg_postinst() scripts need to start with "#!/bin/sh -e"?

[Robert P. J. Day]

  more manual pedantry -- dev manual, section 5.3.16, suggests:

 A post-installation function has the following structure:

     pkg_postinst_PACKAGENAME() {
     #!/bin/sh -e
     # Commands to carry out
     }

except that every example of a pkg_postinst() script i've ever seen
does not contain that initial hash-bang line, so the manual should at
least be reworded to be consistent with the code base.
