[PATCH] gdb/testsuite: add untested message to skip_debuginfod_tests

[Enze Li <enze.li@hotmail.com>]

When running the fetch_src_and_symbols.exp, I see the following output
which looks weird.  I even don't know whether the execution was successful.
======
Running /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.debuginfod/fetch_src_and_symbols.exp ...
testcase /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.debuginfod/fetch_src_and_symbols.exp
completed in 0 seconds

                === gdb Summary ===

======

It is the fact that there's not enough feedback provided during the
skip_debuginfod_tests procedure.  Fix this by adding some untested
messages to the skip_debuginfod_tests procedure to clarify the output.

With this patch applied, I get:
======
Running /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.debuginfod/fetch_src_and_symbols.exp ...
UNTESTED: gdb.debuginfod/fetch_src_and_symbols.exp: cannot find debuginfo
testcase /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.debuginfod/fetch_src_and_symbols.exp
completed in 0 seconds

                === gdb Summary ===

 # of untested testcases         1
======

I also modernized the form of 'if' with 'if {} {}' in
skip_debuginfod_tests.

Tested on x86_64-linux.
