Don't mix definitions and expressions in SRFI-9
The expansion of `define-inlinable' contained an expression, which made
SRFI-9's `define-record-type' fail in non-toplevel contexts ("definition
used in expression context").
* module/srfi/srfi-9.scm (define-inlinable): Get rid of apparently
useless expression in the expansion, so the expansion yields only
definitions. At the same time, use a space in the generated names to
lessen the chances of name conflicts, also avoiding -Wunused-toplevel
warnings.
* test-suite/tests/srfi-9.test (non-toplevel): New test verifying that
`define-record-type' works in non-toplevel context as well.
* doc/ref/srfi-modules.texi (SRFI-9 - define-record-type): Add
subsubsection noting that Guile does not enforce top-levelness.
