decompressor: provide missing prototypes
The entry points for the decompressor don't always have a prototype included in the .c file: lib/decompress_inflate.c:42:17: error: no previous prototype for '__gunzip' [-Werror=missing-prototypes] lib/decompress_unxz.c:251:17: error: no previous prototype for 'unxz' [-Werror=missing-prototypes] lib/decompress_unzstd.c:331:17: error: no previous prototype for 'unzstd' [-Werror=missing-prototypes] Include the correct headers for unxz and unzstd, and mark the inflate function above as unconditionally 'static' to avoid these warnings.
