[OE-core] [PATCH][v4] mmc-utils: fix the building failure when DEBUG_BUILD is 1

[rongqing.li at windriver.com]

From: Roy Li <rongqing.li at windriver.com>

AM_CFLAGS in Makefile includes -D_FORTIFY_SOURCE=2 which will lead
to building failure when DEBUG_BUILD is 1.
Cancel the definition of _FORTIFY_SOURCE by passing -U_FORTIFY_SOURCE
via CFLAGS
