Subject: bug#53657: inconsistent parsing of the channel sexp's

pull.scm does this with channel files, e.g. with /etc/guix/channels.scm:

(load* file (make-user-module '((guix channels))))

i.e. this way field values are EVAL'd. beside the big can of worms that this opens up, it also means that e.g. the name field must be quoted: (name 'guix).

then at other occurrences of channels, an sexp parser is used to read them, e.g. in the 'dependencies field of a .guix-channel entry. see READ-CHANNEL-METADATA in guix/channels.scm.

here the name field is not EVAL'd, and thus it must be specified without quotes: (name guix).

this leads to an actual issue that channel dependencies don't match up, unless the name is without quotes in the dependencies list specification.
