Maxime Hadjinlian d2ff818bc5 fakeroot: fix spurious message "undefined symbol"
Since the glibc 2.24-3, and this commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=80f87443eed17838fe453f1f5406ccf5d3698c25
fakeroot will print spurious message about symbols not being found.

[...]
dlsym(acl_get_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_fd
dlsym(acl_get_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_file
dlsym(acl_set_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_set_fd
dlsym(acl_set_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_set_file
dlsym(acl_get_fd): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_fd
dlsym(acl_get_file): /usr/lib/libfakeroot/libfakeroot.so: undefined symbol: acl_get_file
[...]

It doesn't seem to impair the behavior of fakeroot, it's simply annoying
for the user.

Debian (which is the creator of fakeroot) has a patch which is a
workaround: simply don't display the message.

Note if you wish to bump fakeroot:
A new version is available but the release tarball doesn't include the
'configure' and 'Makefile' pre-generated.
This means that if we were to bump, the package would need to run its
own 'bootstrap' script which will add dependencies to
host-{automake,autoconf,...} which would be annoying (since almost every
build runs fakeroot).

Description: Hide error from dlsym()
dlsym(), starting in glibc 2.24 actually reports errors. In our case,
we try to get ACL functions which are not in the glibc. This causes
failures in test suites, so hide those messages for non-debugging
purposes for now. It also makes the build logs annoying to read.
