meson: only detect ICONV_OMITS_BOM if possible

In our Meson setup it automatically detects whether ICONV_OMITS_BOM
should be defined. To check this, a piece of code is compiled and ran.

When cross-compiling, it's not possible to run this piece of code. Guard
this test with a can_run_host_binaries() check to ensure it can run.
