gdb/fortran: Change whitespace when printing arrays

This commit makes the whitespace usage when printing Fortran arrays
more consistent, and more inline with how we print C arrays.

Currently a 2 dimensional Fotran array is printed like this, I find
the marked whitespace unpleasant:

  (( 1, 2, 3) ( 4, 5, 6) )
    ^          ^        ^

After this commit the same array is printed like this:

  ((1, 2, 3) (4, 5, 6))

Which seems more inline with how we print C arrays, in the case of C
arrays we don't add extra whitespace before the first element.

gdb/ChangeLog:

	* f-valprint.c (f77_print_array_1): Adjust printing of whitespace
	for arrays.

gdb/testsuite/ChangeLog:

	* gdb.fortran/array-slices.exp: Update expected results.
	* gdb.fortran/class-allocatable-array.exp: Likewise.
	* gdb.fortran/multi-dim.exp: Likewise.
	* gdb.fortran/vla-type.exp: Likewise.
	* gdb.mi/mi-vla-fortran.exp: Likewise.
