Test-case gdb.debuginfod/fetch_src_and_symbols.exp leaks env vars
DEBUGINFOD_URLS, DEBUGINFOD_TIMEOUT and DEBUGINFOD_CACHE_PATH, causing
timeouts in subsequent tests.
Fix this by using save_vars. Also, fix PATH and DUPLICATE errors. Finally,
cleanup whitespace.

gdb.debuginfod/fetch_src_and_symbols.exp attempts to ascertain
whether GDB was built with debuginfod support by executing
"$GDB --configuration".
That seems harmless enough. However, if GDB is not already installed
on the host, the command will fail:
$ ./gdb --config
Exception caught while booting Guile.
Error in function "open-file":
No such file or directory: "/usr/share/gdb/guile/gdb/boot.scm"
./gdb: warning: Could not complete Guile gdb module initialization from:
/usr/share/gdb/guile/gdb/boot.scm.
Limited Guile support is available.
Suggest passing --data-directory=/path/to/gdb/data-directory.
Python Exception <class 'ModuleNotFoundError'> No module named 'gdb':
./gdb: warning:
Could not load the Python gdb module from `/usr/share/gdb/python'.
Limited Python support is available from the _gdb module.
Suggest passing --data-directory=/path/to/gdb/data-directory.
This GDB was configured as follows:
configure --host=x86_64-redhat-linux-gnu --target=x86_64-redhat-linux-gnu
[abbreviated output]
The problem here is, of course, that while running in the test suite,
we must pass INTERNAL_GDBFLAGS in order to pick up the --data-directory
option.

* gdb.deuginfod/fetch_src_and_symbols.exp: Pass INTERNAL_GDBFLAGS
when executing "gdb --configuration".

debuginfod is a lightweight web service that indexes ELF/DWARF debugging
resources by build-id and serves them over HTTP.
This patch enables GDB to query debuginfod servers for separate debug
files and source code when it is otherwise not able to find them.
GDB can be built with debuginfod using the --with-debuginfod configure
option.
This requires that libdebuginfod be installed and found at configure time.
debuginfod is packaged with elfutils, starting with version 0.178.
For more information see https://sourceware.org/elfutils/.
Tested on x86_64 Fedora 31.
