lto-ltrans-cache: Remove unused private member

When building GCC with clang, it warns that the private member suffix
in class ltrans_file_cache (defined in lto-ltrans-cache.h) is not used
which indeed looks like it is the case.  This patch therefore removes
it along with its initialization in the constructor.

gcc/ChangeLog:

2025-06-24  Martin Jambor  <mjambor@suse.cz>

	* lto-ltrans-cache.h (class ltrans_file_cache): Remove member prefix.
	* lto-ltrans-cache.cc (ltrans_file_cache::ltrans_file_cache): Do
	not initialize member prefix.
