bug#62329: 30.0.50; Error in TRAMP due to variable aliasing

[Eshel Yaron via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

The recent rename of tramp-use-ssh-controlmaster-options in commit
1c39347d585 seems to cause some problems, namely Emacs now fails with an
error when trying to load tramp-sh (which happens automatically in some
TRAMP flows) if tramp is already loaded and compilation-mode-hook ran.
To reproduce:

1. emacs -Q
2. (require 'tramp)
   This further requires tramp-integration which adds a function
   called tramp-compile-disable-ssh-controlmaster-options to
   compilation-mode-hook
3. Do something that runs compilation-mode-hook, e.g. M-x compile with
   some dummy compilation command like "true".
4. Try to load tramp-sh with e.g. (require 'tramp-sh)
   Emacs fails with an error saying:
   "Don’t know how to make a buffer-local variable an alias:
   tramp-use-connection-share".
   AFAIU This happens because at this point tramp-use-connection-share is
   already a localized symbol and tramp-sh tries to call defvaralias on it.

Thanks,
Eshel
