[bug#63383] [PATCH 4/4] Use more file-append.

[Felix Lechner]

Based on the author's review of the code base as well as past commits, similar
invocations are in the process of being changed over from string-append to
file-append.

* gnu/services/authentication.scm
* gnu/services/base.scm
* gnu/services/kerberos.scm
* gnu/services/pam-mount.scm: Use more file-append instead of string-append.
