compile jsvc in own subshell with explicit LD_LIBRARY_PATH with /lib(32|64) appended

Apparently there is an issue with jsvc picking up the libcap.so
library.  Once upon a time it was in /usr/lib, now it is in
/lib(32|64), so adding to the LD_LIBRARY_PATH in hopes it gets picked
up and avoids tomcat jsvc build problem - as reportd by Luca:

- the most serious issue is that after upgrading Tomcat to 6.0.36,
  JSVC fails to start on my server because of missing
  /usr/lib.libcap.so. I had to manually symlink that library to get
  Tomcat started (see below)

o) issue: missing libcap.so prevents JSVC from starting:

failed loading capabilities library -- /usr/lib/libcap.so: cannot open shared object file: No such file or directory.
Cannot set group id for user 'tomcat'
set_user_group failed for user 'tomcat'
Service exit with a return value of 4

solution:
bash-3.2# ln -s /lib64/libcap.so /usr/lib/libcap.so

bash-3.2# ls -l /usr/lib/libcap.so
lrwxrwxrwx 1 root root 16 Apr 22 07:42 /usr/lib/libcap.so -> /lib64/libcap.so

----------
Instead of linking the library since it goes by the name of
libcap.so.2.  Currently if we can find the library, it should have the
same result.  (put it where it can be found vs let where it is be
known)
Move tomcat security related files to esg's config root

You should not have to get new certificates, etc. when updating or
installing a new tomcat.  These files should be considered part of the
node's "state" and thus held under /esg.

The server.xml file is adjusted accordingly to look at the
/esg/config/tomcat location for certificates and users.

Ex:

/esg/config/tomcat
