Fixes <https://issues.guix.gnu.org/61722>.
* guix/cpio.scm (file->cpio-header): Compute the file name length in bytes
rather than in
characters.
(file->cpio-header*, special-file->cpio-header*): Likewise.
(write-cpio-archive): Likewise, and write the file name as UTF-8 bytes, not
textually, to avoid encoding it as ISO-8859-1.
---
Changes in v2:
- Use string-utf8-length
