Guile 3.0.11 introduced a new implementation of (srfi srfi-34) with subtle
changes wrt. exceptionm handling.  This adjusts to these changes.

Changes in ‘tests/style.scm’ are due to the new output of (ice-9 pretty-print)
in 3.0.10.

* tests/file-systems.scm ("btrfs-store-subvolume-file-name (subvolid)"):
Specify the exception type.
* tests/services/file-sharing.scm ("transmission-password-hash, salt value too short")
("transmission-password-hash, salt value too long"): Likewise.
* tests/store.scm ("store-path-package-name #f"): Change to ‘test-error’
with #t as the exception type.
* tests/style.scm: Skip all the tests on Guile > 3.0.9.
* tests/toml.scm <top level>: Set ‘raise’ in (guix build toml).
("parse-toml: No key"): Use ‘test-error’ instead of ‘test-equal’.
("parse-toml: Assignment to non-table"): Likewise.
("parse-toml: Invalid assignment to implicit table"): Change exception type
to #t
("parse-toml: Assignment to statically defined array"): Likewise.
