libc: Improve CAF libc wrapper flag config

The CAF changes 0ca32a9 and 153ed5a
were made following a wrong logic,
thinking that CFLAGS are not getting
applied to CPP files.
In reality CFLAGS get applied to C
and CPP files.

Applying "USE_WRAPPER" to CPP files
only is potentially unsafe, since
the header "unistd.h" picks it up
and its "write" method definition
can be picked up by C files too.

This patch converts "USE_WRAPPER"
to be applied on C and CPP files
in the needed cases and removes
redunant definitions which result
from this change.
