LU-17301 utils: l_getidentity build fix

The extra shared libs dependencies have an effect on
the l_getidentity libtool wrapper script created
in the source directory. The wrapper script fails
if it is executed as an identity upcall by a Lustre
md server, as it uses some of the core linux utilities
from /bin:

l_getidentity: line 150: ls: command not found
l_getidentity: line 197: rm: command not found
l_getidentity: line 211: rm: command not found
l_getidentity: line 212: mv: command not found
l_getidentity: line 213: rm: command not found

Removing the unnecessary build dependencies fixes
the issue.
