android: Fix build of libmesa_program

Commit 4097308 fixed the build in a questionable way. It worked at the
time, but, as Ian pointed out, the fix would likely fail at a future
commit due to the indeterminism of parallel builds. And that's exactly
what happened; the fix no longer works. `mm -j4` on Fedora 17 fails for
me.

The problem is that there is no rule for program_parse.tab.h. To fix that,
this patch adds a rule that makes program_parse.tab.c depend on
program_parse.tab.h. Technically, the c file does not depend on the
h file. However, because the two files are generated together by a single
invocation of Bison, any rule that forces execution of Bison is
sufficient.
