    [gdb/testsuite] Fix gdb.cp/m-static.exp regression on Ubuntu 20.04

    In commit 722c4596034 ("[gdb/testsuite] Fix gdb.cp/*.exp for remote host"),
I
    needed to change ".*/" into "(.*/)?" in:
    ...
    gdb_test "info variable everywhere" \
        "File .*/m-static\[.\]h.*const int gnu_obj_4::everywhere;"
    ...

    However, due to the fact that I got this output:
    ...
    (gdb) info variable everywhere^M
    All variables matching regular expression "everywhere":^M
    ^M
    File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
    8:      const int gnu_obj_4::everywhere;^M
    ^M
    File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static1.cc:^M
    8:      const int gnu_obj_4::everywhere;^M
    ...
    I decided to make the matching somewhat stricter, to make sure that the two
    matched lines were subsequent.

    The commit turned out to be more strict than intended, and caused a
regression
    on Ubuntu 20.04, where the output was instead:
    ...
    (gdb) info variable everywhere^M
    All variables matching regular expression "everywhere":^M
    ^M
    File /data/vries/gdb/src/gdb/testsuite/gdb.cp/m-static.h:^M
    8:      const int gnu_obj_4::everywhere;^M
    ...

    At that point I realized I'm looking at a bug (filed as PR symtab/30265),
    which manifests on openSUSE Leap 15.4 for native and readnow, and on Ubuntu
    20.04 for readnow, but not for native.

    Before my commit, the test-case passed whether the bug manifested or not.

    After my commit, the test-case only passed when the bug manifested.

    Fix the test-case regression by reverting to the situation before the
commit:
    pass whether the bug manifests or not.  We could add an xfail for the PR,
but
    I'm expecting a fix soon, so that doesn't look worth the effort.

    Tested on x86_64-linux, both on openSUSE Leap 15.4 and Ubuntu 20.04, both
with
    native and readnow.
