when there's a syntax error in a scriptlet, it shows the name of the temp file

[Leo Arias]

When there's a syntax error in a scriptlet, it shows the name of the temp file which is not useful at all to find the error.

To reproduce:

Put a part with this in a snapcraft.yaml

    plugin: nil
    prepare: |
      echo "hola" &&

There is a syntax error at the end of prepare because it's missing the second statement.
Run snapcraft:

$ snapcraft
Preparing to pull my-part
Pulling my-part
Preparing to build my-part
Building my-part
/tmp/tmpnpz33nrs: 2: /tmp/tmpnpz33nrs: Syntax error: end of file unexpected
Command '['/bin/sh', '/tmp/tmpgasuc_zd', '/tmp/tmpnpz33nrs']' returned non-zero exit status 2

Instead of showing the name of the tmp file, the error should point to the prepare scriptlet in the yaml.
