macOS build error: no execvpe

[schmonz]

With "1.7" (at commit 329110310c71a08a942b4a36613b6db090df65f4) on macOS Big Sur x86_64:

clang -O2 -I/opt/pkg/include -D_DARWIN_C_SOURCE -std=c99 -pedantic -Wall -Wextra -D_XOPEN_SOURCE=700 -D_BSD_SOURCE -I/opt/pkg/include  -c -o tlsc.o tlsc.c
tlsc.c:256:3: warning: implicit declaration of function 'execvpe' is invalid in C99 [-Wimplicit-function-declaration]
                execvpe(prog, argv, environ);
                ^
1 warning generated.
clang -L/opt/pkg/lib -lcrypto `pkg-config --libs libtls libssl` -o tlsc tlsc.o -ltls `pkg-config --libs libssl`
Undefined symbols for architecture x86_64:
  "_execvpe", referenced from:
      _main.cold.23 in tlsc.o
ld: symbol(s) not found for architecture x86_64

I have no idea whether this workaround is correct, but it gets us past the build error:

Tribblix m25 also lacks execvpe().

Also happy to provide SSH access to a macOS host (for this and #10).

Fixed. Thanks for the suggestion.
