[PATCH] emit EXTRA_DIST unconditionally so tarball does not depend on configured platform

[Andrey Borzenkov <arvidjaar@gmail.com>]

Currently extra_dist sources are emitted under enabled platform conditions.
So if module/image/... is not enabled for every platform, extra_dist files
will not be included in tarball during "make dist" if module is not enabled
for currently configured platform. As example, attempt to build i386-pc from
tarball created under x86_64-efi fails with:

make[3]: Entering directory `/home/bor/build/grub/grub-2.00/grub-core'
gcc -DHAVE_CONFIG_H -I. -I..  -Wall -W -I../include -I../include  -DGRUB_MACHINE_PCBIOS=1 -DGRUB_MACHINE=I386_PC -DGRUB_TARGET_CPU_I386=1 -m32 -nostdinc -isystem /usr/lib64/gcc/x86_64-suse-linux/4.7/include -DGRUB_FILE=\"efiemu/loadcore32.c\" ...  -c -o efiemu/efiemu_module-loadcore32.o `test -f 'efiemu/loadcore32.c' || echo './'`efiemu/loadcore32.c
efiemu/loadcore32.c:22:22: fatal error: loadcore.c: No such file or directory
compilation terminated.

Change gentpl.py to emit dist_noinst_DATA instead. Automake collects them
even when assignment is under false condition, so it ensures tarball always
includes the same files on every platform.

It also changes data to emit dist_<directory>_DATA instead of using EXTRA_DIST.
