Subject: [PATCH] Build: Add separate header install/uninstall targets

Two new Makefile targets have been added... "install-headers" and
"uninstall-headers" to separately control header installation.
The existing behavior has not changed so "make install" and
"make uninstall" will continue to also install/uninstall the headers.
The new targets were added for forward compatibility with Asterisk 17
in which the headers are no longer installed/uninstalled with the
"install" and "uninstall" targets.

Also corrects an issue where /usr/include/asterisk.h was never
being removed at all.
