[PATCH 2/2] gdb/guile: remove unused escape_symbol variable

[Simon Marchi <simon.marchi@efficios.com>]

Building GDB with a recent clang fails with:

    /home/smarchi/src/binutils-gdb/gdb/guile/scm-value.c:78:12: error: variable 'escape_symbol' set but not used [-Werror,-Wunused-but-set-global]

value->string only accepts 'error and 'substitute for its #:errors
argument, so the 'escape symbol is never used.  It has been unused since
commit ed3ef33944c3 ("Add Guile as an extension language.",
2014-02-09).  Remove it.
