[oe] [meta-oe][PATCH] rsyslog: fix race in parallel builds

[Hongxu Jia]

If libgcry.la is built later than lmcry_gcry.la, there is a failure:
[snip]
|../aarch64-wrs-linux-libtool  --tag=CC   --mode=link aarch64-wrs-linux-gcc
-o lmcry_gcry.la lmcry_gcry_la-lmcry_gcry.lo libgcry.la -lgcrypt
|aarch64-wrs-linux-libtool:   error: cannot find the library 'libgcry.la'
or unhandled argument 'libgcry.la'
|Makefile:1049: recipe for target 'lmcry_gcry.la' failed
|make[2]: *** [lmcry_gcry.la] Error 1
[snip]

The LIBADD of lmcry_gcry.la contains libgcry.la, we should also add libgcry.la
to lmcry_gcry.la's DEPENDENCIES.
