Fix AMDuProfPcm so it finds libnuma.so

Browse Source 
We change the search procedure so it detects NixOS from /etc/os-release
and uses "libnuma.so" when calling dlopen, instead of harcoding a full
path to /usr. The full patch of libnuma is stored in the runpath, so
dlopen can find it.

# Patch arguments to call sym std::string::find(char const*, unsigned long, unsigned long)
# so it matches NixOS:

# Change OS name to NixOS
wz NixOS @ 0x00550a43
# And set the length to 5 characters
wa mov ecx, 5 @0x00517930

# Then change the argument to dlopen() so it only uses libnuma.so
