[PATCH v2 2/8] file2alias: fix uuid_t definitions for macos

From: Daniel Gomez <da.gomez at samsung.com>

The uuid_t struct defined in sys/types.h on macOS hosts conflicts with
the one defined in file2alias, resulting in the typedef redefinition
error below. To resolve this conflict, define the _UUID_T and
__GETHOSTUUID_ in file2alias HOSTCFLAGS.

Error:
