[PATCH 16/19] Mark ld.so internel mmap functions hidden

[H.J. Lu]

Since ld.so internel mmap functions are only used internally in ld.so,
they can be made hidden.

	 [BZ #19122]
	 * include/sys/mman.h [IS_IN (rtld)] (__mmap): Add
	 attribute_hidden.
	 [IS_IN (rtld)] (__mprotect): Likewise.
	 [IS_IN (rtld)] (__munmap): Likewise.
