bionic: introduce libc.debug.malloc.program

libc.debug.malloc.program  provides an additional level of control over which
processes to enable libc.debug.malloc functionality for.  The string value of
libc.debug.malloc.program is matched against the program name; if the value of
libc.debug.malloc.program is a substring of the program name, then malloc debug
is applied to that program at whatever level libc.debug.malloc specifies.

If lib.debug.malloc.program is not specified, then libc.debug.malloc has the
same effect as before.

For example, to enable libc.deubug.malloc = 10 only to the mediaserver, do the

   adb root # necessary for setprop
   adb setprop libc.debug.malloc.program mediaserver
   adb setprop libc.debug.malloc 10
   adb kill -9 $(pid mediaserver)
