[PATCH 22/27] gdb.base/maint-info-sections.exp: Match exec file name with optional .exe

Two tests of gdb.base/maint-info-sections.exp match a header line
against the expected binary name:

 1. The "maint info sections" test matches the "Exec file:" header
    with:

      Exec file: .*${binfile}., file type...

    where the trailing "." is meant to match the closing quote after
    the file name.

 2. The "maint info sections -all-objects" test matches the "Object
    file:" header, expecting the closing quote immediately after
    $binfile.  Both assume the printed name is exactly $binfile.

But on a host where the executable has a ".exe" suffix that is not
part of $binfile, the printed name is "$binfile.exe", so neither
header matches: the single "." matches the dot instead of the quote,
and the "Object file:" quote does not line up at all.  The tests then
fail, e.g., on x86_64-w64-mingw32:

  FAIL: gdb.base/maint-info-sections.exp: maint info sections
  FAIL: gdb.base/maint-info-sections.exp: maint info sections -all-objects

Fix this by allowing for an optional ".exe" between the file name and
the closing quote in both, matching the closing quote explicitly.

Tested on:

 x86_64-pc-linux-gnu
 x86_64-pc-cygwin
 x86_64-w64-mingw32
 x86_64-pc-windows-msvc
