package_rpm: Add optional improved directory handling

During spec generation, ideally directories should not be auto
packaged under the %file section of rpm packages but take ownership of
specific directories.

* packages only empty directories or explict directory.
   See:
       - http://www.rpm.org/max-rpm/s1-rpm-inside-files-list-directives.html
       - "The %dir Directive"

* This will prevent the overlapping of security permission.
   For example, in Tizen the directory /etc have smack label 'System::Shared'
   So Only one package should own and set the label of /etc to prevent
   the overwriting of the smack label.

Existing behaviour is maintained if DIRFILES is not set. If it is set,
the modified behaviour is used. If can be set to an empty value by
core recipes to trigger the modified behaviour.

[RP: Modified to allow optional usage of DIRFILES]

useradd-staticids.bbclass: Fix for Bug 6633

When using the useradd-staticids.bbclass under meta/classes,
this error occurs:
"<username> - <username>: Username  does not have a static uid defined."
There was a problem with the regular expression for parsing parameters,
it was sometimes returning an empty string.

I have fixed this by skipping empty strings.

systemtap: Cross compilation fix

This is a cross compilation fix. It allows systemtap to find the
kernel map file in the right place, i.e. in the kernel build tree.
Without this fix it takes a map file from the build host, if available.

rpmresolve: ignore null requires

It is not a problem if a package requires nothing (similar to RDEPENDS
is null), for example, these packages depends on nothing:

[snip]
alsa-conf-base
base-files
eglibc-binary-localedata-en-us
xserver-xf86-config
[snip]

The rpmresolve-native's algorithm is:
===fake code
for pkg in pkg1, pkg2, pkg3:
    rc = get_req(pkg)
return rc
===fake code

Suppose of the 3 pkgs requires null:
- We are lukcy if pkg1 or pkg2 is null, nothing happend.
- We are *not* lukcy if pkg3 is null, and will get the error when "INHERIT +=
  'buildhistory'":
  ERROR: Cannot get the package dependencies. Command
  '/path/to/x86_64-linux/usr/bin/rpmresolve -t /path/to/var/lib/rpm' returned 1:

This patch fixes the problem.
