[PATCH] security_flags.inc: remove obsolete workarounds for curl

[Andre McCurdy <armccurdy@gmail.com>]

The curl configure script contains sanity checks for unexpected
options being passed via CFLAGS, LDFLAGS, etc. environment variables.

These sanity checks catch -Dxxx options in CFLAGS, which clashes with
OE's approach of using CFLAGS to pass -D_FORTIFY_SOURCE (curl's
configure script suggests, quite correctly, that -Dxxx options should
be passed via CPPFLAGS instead).

These sanity checks previously generated fatal errors, but have been
downgraded to warnings since curl v7.32. Therefore the workaround of
avoiding -D_FORTIFY_SOURCE for curl is obsolete and can be removed.
