[BUG] Geiser fails to start REPL on Emacs 26

[BUG] Geiser fails to start REPL on Emacs 26

[Ihor Radchenko]

Hi,

Our (Org mode) CI is now failing to run ob-scheme tests because Geiser
fails to run REPL:

https://builds.sr.ht/~bzg/job/1035753

Test test-ob-scheme/tables backtrace:
  (obsolete max-specpdl-size)()
  geiser-syntax--read-from-string("#<unspecified>")
  geiser-guile-update-warning-level()
  geiser-guile--startup(nil)
  apply(geiser-guile--startup nil)
  geiser-impl--call-method(repl-startup guile nil)
  geiser-repl--startup(guile nil)
  geiser-repl--start-repl(guile nil)
  geiser(guile)
  org-babel-scheme-get-repl(guile nil)

This happens because `geiser-syntax--read-from-string' tries to call
`with-suppressed-warnings', which is only available starting from Emacs
27.

Considering that geiser claims supporting Emacs >=25.1, this appears to
be a bug.

Hi.  Thanks for the heads up. I've upped the requirement in Geiser 0.29.1
to Emacs 27.1.

Cheers,
jao

Thanks!
I am thus disabling ob-scheme tests for Emacs <27.1.

Fixed, on bugfix.
