[libc] Switch to use a macro which does not insert a section for every libc function.

Summary:
The new macro also inserts the C alias for the C++ implementations
without needing an objcopy based post processing step. The CMake
rules have been updated to reflect this. More CMake cleanup can be
taken up in future rounds and appropriate TODOs have been added for them.

[libc] Move the implementation of mmap and munmap into a linux specific area.

This allows us to get rid of the PAGE_SIZE macro and use EXEC_PAGESIZE
from linux/param.h.

Few other points about this change:
1. The linux syscall functions have been moved into a linux specific area
instead of src/unistd/syscall.h. The Linux syscall function from unistd.h
is a public vararg function. What we have currently are linux speciif internal
overloaded C++ functions. So, moving them to a Linux only area is more
meaningful.
2. The implementations of mmap and munmap are now in a 'linux' directory
within src/sys/mman. The idea here is that platform specific
implementations will live in a platform specific subdirectories like these.
Infrastructure common to a platform will live in the platform's config
directory. For example, the linux syscall implementations live in
config/linux.
