strings: ".. (compression)? is not supported by this build"

$ git grep 'is not supported by this build' '*c'
src/backend/access/transam/xloginsert.c: elog(ERROR, "LZ4 is not supported by this build");

src/backend/replication/basebackup_zstd.c: errmsg("zstd compression is not supported by this build")));

Should the word "compression" be removed from basebackup, for consistency with
the use in xloginsert.c ? And "lz4" capitalization changed for consistency (in
one direction or the other). See 4035cd5d4, e9537321a7, 7cf085f07. Maybe zstd
should also be changed to Zstandard per 586955ddd.

To avoid the extra translation, and allow the compiler to merge strings.

The "binary size" argument wouldn't apply, but note that pg_dump uses this
language:

src/bin/pg_dump/compress_io.c: pg_fatal("not built with zlib support");

See also some other string messages I mentioned here:
