sh-i18n--envsubst.c: do not #include getopt.h

The getopt.h header file is not used. It's inclusion is left over from the
original version of this source. Additionally, getopt.h does not exist on
all platforms (SunOS 5.7) and will cause a compilation failure. So, let's
remove it.

show_variables is set but never used. Comment it out rather than remove it so
that the relation with upstream remains clear.

Add a git-sh-i18n--envsubst program which is a stripped-down version
of the GNU envsubst(1) program that comes with GNU gettext for use in
the eval_gettext() fallback.
We need a C helper program because implementing eval_gettext() purely
in shell turned out to be unworkable. Digging through the Git mailing
list archives will reveal two shell implementations of eval_gettext
that are almost good enough, but fail on an edge case which is tested
for in the tests which are part of this patch.
These are the modifications I made to envsubst.c as I turned it into
sh-i18n--envsubst.c:
* Added our git-compat-util.h header for xrealloc() and friends.
* Removed inclusion of gettext-specific headers.
* Removed most of main() and replaced it with my own. The modified
version only does option parsing for --variables. That's all it
needs.
* Modified error() invocations to use our error() instead of
error(3).
* Replaced the gettext XNMALLOC(n, size) macro with just
xmalloc(n). Since XNMALLOC() only allocated char's.
* Removed the string_list_destroy function. It's redundant (also in
the upstream code).
* Replaced the use of stdbool.h (a C99 header) by doing the following
replacements on the code:
* s/bool/unsigned short int/g
* s/true/1/g
* s/false/0/g
