Make sure we do pass TARGET_CPPFLAGS using CPPFLAGS (which is supported
by sslh's Makefile), fixing build issues with some external toolchains:

mipsel-linux-gnu-gcc -Os -pipe -mno-branch-likely -mips32r2 -mtune=24kc
-fno-caller-saves -Wno-unused-result  -D_FORTIFY_SOURCE=1 -Wl,-z,now
-Wl,-z,relro -DENABLE_REGEX -DLIBCONFIG -c sslh-main.c
sslh-main.c:26:23: fatal error: libconfig.h: No such file or directory
 #include <libconfig.h>
                       ^
compilation terminated.
Makefile:63: recipe for target 'sslh-main.o' failed
make[4]: *** [sslh-main.o] Error 1

This allows users to use an external config file if required (for
example matching packets based on SNI hostname or REGEX patterns).

Backport upstream commit 3aefaf3 which allows sslh to be built without
libpcre support. This was brought about by the move to musl which
doesn't support the non-POSIX REG_STARTEND regexec eflag.

Fixes: #1506

Replace the MAINTAINER lines in packages that I maintain with
PKG_MAINTAINER lines, to be consistent with the rest of the packages
tree.
