[Buildroot] [PATCH] alsa-utils: disable manpages generation from reStructured text

[Baruch Siach]

The alsaucm man page rst source file is missing in the tarball. When rst2man
is detected on the host, build fails:

make[2]: *** No rule to make target 'alsaucm.1', needed by 'all-am'.  Stop.

Upstream added[1] the missing file to the tarball to fix this issue. But since
we don't need the manpage to begin with, just disable rst2man to shorten build
time by a few milliseconds.
