Followup to <http://issues.guix.gnu.org/issue/26175#4>:

guix shall print a hint if building fails due to the package source base
name containing a character invalid in a store filename (e.g. "@" or "%")=
.

Currently, when building such a package, one gets an error message like:

guix build: error: invalid character `@' in name
`kde-l10n-ca@HIDDEN'

guix build should catch this error and print a hint like:

You may add a =E2=80=98file-name=E2=80=99 field to the package source to =
work around this.
