bug#4992: Invalid use of strcpy() in etags

User-agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.1.4pre) Gecko/20090922 Fedora/3.0-3.9.b4.fc12 Thunderbird/3.0b4

The function absolute_filename() lib-src/etags.c has two invalid calls to strcpy() with overlapping arguments. It's undefined C that often happens to work, but breaks very badly for at least gcc 4.4.2 and glibc 2.11 on x86_64, which is default for Fedora 12.

The attached patch replaces the bogus strcpy() calls with calls to memmove().
