@btnBorder variable has no effect

See the comment:

button border color (@btnBorder) is always overridden by the reset. .btn border-color is first set to #c5c5c5 then second directive with transparency is applied.

Seems that @btnBorder should be updated to #c5c5c5 and the extra .btn border reset removed, but that would subtly change the existing button border.

My current hack is to add this to my build:

.btn {
  border-color: @btnBorder;
  border-bottom-color: darken(@btnBorder, 10%);
};

Issues seems fairly self-evident from buttons.less, but let me know if I need a more detailed test case.

Fixed in #6346. Thanks!
