Mark 3 *_internal functions with attribute_hidden [BZ #18822]

Browse Source 
Mark __ptsname_internal, __mktime_internal and __fopen_internal with
attribute_hidden to allow direct access to them within libc.so and
libc.a without using GOT nor PLT.

	[BZ #18822]
	* include/stdlib.h (__ptsname_internal): Add attribute_hidden.
	* include/time.h (__mktime_internal): Likewise.
	* libio/iolibio.h (__fopen_internal): Likewise.
