tar: add IF_FEATURE_* checks
A following linking error was observed:
| ==========
| archival/lib.a(tar.o): In function `tar_main':
| archival/tar.c:1168: undefined reference to `unpack_Z_stream'
| archival/tar.c:1168: undefined reference to `unpack_Z_stream'
| ld: busybox_unstripped: hidden symbol `unpack_Z_stream' isn't defined
| ld: final link failed: Bad value
this happened with clang compiler, with the following configs:
| CONFIG_TAR=y
| # CONFIG_FEATURE_SEAMLESS_Z is not set
which can be fixed by adding IF_FEATURE_* checks in.
