Fix ascent and descent of Droid Sans Mono to match Roboto.

Previously, the inconsistency resulted in test in the testUniformY in
frameworks/base/graphics/tests/graphicstests/src/android/graphics/TypefaceTest.java
fail. The tests assume the different sans/serif/mono styles share a
consistent ascent and descent.

The font is modified using the following Python script:

from fontTools import ttLib

font_file = 'DroidSansMono.ttf'
font = ttLib.TTFont(font_file)
font['hhea'].ascent = 1900
font['hhea'].descent = -500
font.save('touched/'+font_file)
