download: Fix some minor progress-logging regressions.
* guix/build/download.scm (string-pad-middle): Allow resulting padded string to overflow. (store-url-abbreviation): Remove unnecessary procedure. (progress-proc): Use BASENAME as default for parameter 'abbreviation'. (url-fetch): Display extra newlines for readability.
