Fix missing include in nss/nss_db/db-init.c

[Andreas Jaeger]

Compiling on Linux/i586 I get with glibc 2.15 these warnings:
nss_db/db-initgroups.c:60:3: warning: implicit declaration of function 
'strlen' [-Wimplicit-function-declaration]
nss_db/db-initgroups.c:74:7: warning: implicit declaration of function 
'strncmp' [-Wimplicit-function-declaration]
nss_db/db-init.c:46:3: warning: implicit declaration of function 
'strcpy' [-Wimplicit-function-declaration]

db-init.c is already fixed in git head but db-initgroups not.

Fixed with the appended obvious patch, tested on Linux/i386 and 
Linux/x86-64.
