mame: update to 0.276.

MAME 0.276 has arrived just in time for the end of March, and it’s
full of emulation goodness! Remember that 64-bit ARMv8 recompiler
we added a few months ago? Well now it’s even faster! This release
fixes graphical issues in Konami GX arcade games and Philips CD-i
software. We’ve added several IGS gambling games, as well as Chinese
versions of some Dynax mahjong games. The LinnDrum percussion
synthesiser is now working with interactive controls and sound
output. And speaking of sound, audio emulation issues in several
arcade games have been fixed.

PC-88VA emulation is progressing, with fixes for multiple graphics
modes. A few more peripherals for the TI-99 computer family are
now supported. There have been a few CPU/DSP fixes that should
improve Sega 3D arcade game emulation. Psion hand-helds now correctly
detect more memory configurations and give better-looking video
output. We’ve also fixed some issues with CHD creation, floppy disk
image handling, and XML system information output. Windows users
now get an option to have debugger windows appear in the taskbar
and window switcher.
